I want to implement a feature that you can scan an image of reality by your phone, you will generate a feature code from the image, and then upload it to cloud service. If the database of cloud service has this code, you can download something related to the image. Now, the main problem with me, I need a system or cloud service to help me to identify the images, I don't want to do too much things, so is there hava an existing cloud service to support me do that? Free or paid are ok.
Microsoft has launched recently a new set of machine-learning APIs called "Project Oxford" that include functionality for face detection and recognition, speech recognition and synthesis, vision and understanding of natural languages
Face APIs provide state-of-the-art algorithms to process face images, like face detection with gender and age prediction, recognition, alignment and other application level features. For more information, see Project Oxford at www.projectoxford.ai/face.

I will try to be brief and specific here. I want to build a mobile cross platform College News app (that serves android and IOS) which can be used by students at my school of 2,000. This app would likely serve about 500 - 1000 people at its peak and I'm thinking it would have a worker from the news paper office update the articles that go within the app. For its first iteration I want it to be simple as possible.
I was wondering what are the minimum physical or software systems required to make this happen? Currently I think I will need: Google Login API, the app it self, and a server to populate data. Am I missing anything else here? Would I need a database or a physical computer server to support the app? Any input appreciated.
The easiest solution to handle thousands of clients and a server would be to use web technologies. Take a look at Apache Cordova. This is a cross platform solution for iOS, Android and Windows Phone.
Firebase could help you to upload and download news from and to subscribers.
So, yes, this is probably 1000th question on the subject. However, my question is somewhat different from others that were asked about this, so please bear with me:
I am looking to develop a single mobile-app that targets the three/four popular and/or growing mobile platforms (Iphone, Android, WinPhone7, RIM). This application is an extension of an existing SaaS system that my startup currently offers. This mobile-app would provide a quick-and-simple way to view up-to-date status & chart & report information for the data that SaaS application collects. Connection to the internet is required 100%. No data entry besides username/password. App is very simple with 5-6 "pages".
In phase 1, all that would need to be supported is for user to log in, get to see current status of his data stored in the cloud, get access to a few live reports
In phase 2, I'd like to be able to offer push-notification of certain key events from my servers in the cloud
My goals are:
1) The back-end processing that generates data for reports is already written in ASP.NET MVC2. I want to re-use it. It can be exposed as either a WCF service or published on a mobile-friendly website
2) I'd like to be able to deploy the patches faster than through the official app-stores/marketplaces.
3) I cannot afford to spend a lot of resources to target three-four proprietary platforms, for an app that is auxiliary to the vertical purpose of the business. I want to develop it once for all 3-4 platforms.
4) I do not have access, nor do I want to purchase a Macbook
5) I do want to deploy thru the vendor-specific application marketplaces
6) I'd like to stay way from proprietary languages/frameworks/lock-ins
Sounds like what I need is a shell around a mobile-friendly site that can be packaged as an app. Are there existing products that can make it REAL EASY for me to do so? Will doing so, preclude me from doing push notifications in phase 2?
Can anyone recommend a "shell" product that would make a wrapper around the website as well as Javascript library that would look the best across all 4 platforms. I've seen the names like Jqtouch, Jquery Mobile, etc... but not sure which ones are better for what I need.
Do I need PhoneGap? I am not 100% sure here. Can PhoneGap use online-only html/javascript pages to translate into native code or must html/javascript files be distributed with the application? I'd rather have the website itself drive the UI completely, as I can keep changing the website without various version approval processes from vendor market-stores.
Thank you for help
I don’t think you need Phonegap after reading about your project goals. You might consider a Web App instead of a native one if you 1) dont want to buy a mac (required for iOS even tho you can compile it in the cloud: https://build.phonegap.com/), and 2) want to apply and deploy updates anytime without going thru those platform independent marketplaces and approval processes.
jQuery Mobile would be an excellent choice, currently (at this very moment) in Alpha 3 but a very stable one and you can deploy your system on any of those platforms. Note that if you focus your efforts in a Web App you can’t target the second phase you mentioned: Push Notifications.
If you decide going Native, then Push Notifications services can be deployed into your Phonegap project once you setup the proper web services and certificates (take a look # http://easyapns.com);
..and one quick note, the idea of phonegap is that all resources (html, js, images. etc) have to be distributed locally within the app and then getting online data (like reports, etc) using JSON from another web service, and that’s another easy task to accomplish. Phonegap DOES NOT compile your HTML files into native code (ObjectiveC or Java), it just load your Web App into a UIWebKit component at run time (in the case of an iOS app)
Another alternative could be using Titanium - http://www.appcelerator.com but this approach is more javascript oriented and your final app looks much more native. (not HTMLs here so I think thats a drawback for you)
Hope it helps :)
I just heard that a company I do work for may be bringing in the Pyxis Mobile application development system. When I google it most of what I find is from the company's web site and that is not very informative from a geek perspective. Can any one shed some light on what sort of programming environment it is and what programing language is involved (please let there be a text based language). Any additional information would be great.
Note: the company/product changed their name to Verivo in January.
Full Disclosure - I work as an engineer at Pyxis Mobile. However, I have been in the mobile space for 7+ years and have evaluated several approaches to mobile so hopefully this is helpful.
Pyxis Mobile provides a set of tools and components to build cross platform mobile applications. Let me outline them first.
1. Application Studio - All application development, backend integration, user provisioning and application maintenance/debugging is done w/in this tool. Application Studio (for now) is a Windows based desktop app.
2. Application Clients - Pyxis Mobile provides native client runtimes for iPhone, iPad, BlackBerry, and Android devices. These runtimes get branded for the customer through a build service and are primed to point to a specific Application Server URL.
3. Application Server - Pyxis Mobile App Server runs on the .NET stack (on IIS). All client communication is proxied via this server. This server is able to connect to varied of backend systems (via the Plugin Framework listed below) and respond to the client in a mobile optimized manner. This server needs a SQL Server (2005 or newer) for configuration access, session management, logging and more.
4. Plugin Framework - The Plugin Framework is a backend component that provides system specific pre-built access to several of the enterprise and cloud based systems (Oracle, Siebel, SAP, Salesforce.com, social feeds, REST/SOAP web services, etc.) and also offers an API layer in .NET and Python (using IronPython) to allow even further customization. A plugin is essentially comprised of one or more DLLs or a Python file. These assets are then dynamically loaded to normalize communication between Pyxis Mobile and the customers' backend systems.
5. Push Services - This provides a cross-platform push layer that can poll a backend system for change and alert a mobile device via BlackBerry Push, Apple Push Notification Services (APNS) or Android's Cloud to Deice Messaging (C2DM).
6. OverWatch Analytics - This is an optional (but included) component to track users/devices and provide integrated analytics on what the users are using and what kind of devices and locales makes up your users.
The application itself is "coded" via configuration that is build in App Studio. Pyxis Mobile abstracts away from the code so that you can work at a higher level without having to worry about the wide array of device variances (GPS, touch screens, camera, accelerometer, push, screen resolution, etc.). You can drag fields onto a from, connect screens via menus or buttons, set up caching rules and more in this graphical utility. This configuration (essentially think of an XML like document) is interpreted by the native client layer to produce a rich application. There is also a scripting layer in Lua that allows to really customize behavior via code.
The real value of Pyxis Mobile comes up when you have change to make. The clients check for new configuration at app startup or if the server forces the client to get new configuration. This gives you great agility. Lets say once your application is deployed you want start using the swipe gesture to go next/prev through a set of records. This change on other platforms would mean writing some platform specific code to trap and interpret the swipe to perform a navigation (you couldn't trap a swipe on a non-touch screen). However, in Pyxis Mobile this is a simple configuration change that can be quickly deployed to the App Server and the clients automatically download and use the new configuration. No compilation, no redeployment or re-download for the end users.
I could keep going, but hope this provides some level of guidance.
Beware of Pyxis Mobile. While many of the things they say do work, there are some serious platform issues (as a geek) which I've experienced.
1) No version control system process. The Application studio can basically only be developed on by one person at a time or you risk having your changes overwritten by a fellow developer. The "principle of last save" is very much in play.
2) No unit test coverage. This isn't the biggest issue for a lot of people, but it's a concern for anyone who wants to work in the Enterprise world.
3) The middleware server gets you some value, but it's also a PITA to work with. There is no concept of "client side storage" unless you consider the middleware server the client side. If your phone goes out of coverage, your app won't work. Again, this might not be an issue for you.
4) The application has no true scripting language to work with. The middleware server allows you to intercept requests and responses and modify what you're doing there, but it's not the most elegant solution considering that a native application can have something as simple as "if this then X else Y." This can be accomplished with Pyxis, but the whole process is convoluted and more complicated than one would think it needs to be.
5) Lack of documentation. There's some training guides and the GUI is easy enough to get around for simple apps; however, when you need to do something with guts, you're left relying on Pyxis professional services. There's really no developer community to pose questions to.
I have more complaints, but they are more opinion oriented than Q/A oriented.
I just got note about the most recent comments. I don't want to turn this into a thread of back and forth, but did want to throw a couple of quick notes.
Regarding the points on version control and documentation/developer community - no big contest there. We are definitely working on these shortcommings. We have some basic pieces in place, but we have big plans to focus on this.
Regarding unit testing - we provide a very open interface to our middleware and backend components and they can be very easily unit tested with a bit of instrumentation. We run a ton of unit and integration tests internally. However, mobile unit testing is extremely difficult to get right. We'll investigate this further.
Regarding #4 around middleware and offline capabilities - things are a lot different now. With version 7.1, 7.2 and 7.3 our products have increasing become more capabale offline and now features a secure local database if necessary. I can provide more details as necessary, but you can certainly login and operate the app even if you are out of coverage for weeks at a time!
Regarding #5, we've had a scripting engine for over 2 years. Its Lua based and its actually quite powerful and fast. It was BlackBerry only till the most recent release. Given Apple's change of stance on allowing scripting we now allow scripting on BlackBerry, iPad, iPhone and Android as well now!
#RockMeetHardplace - feel free to reach out to me directly and I'll be happy to give you more detailed live demos of our latest platform. I am at - arunSPAMNOTatpyxismobiledotcom (drop the "SPAMNOT" and replace the at and dot). I happen to be the Director of Software and interested in knowing more about the issues you had.
I am developing an ASP.NET intranet application that needs to have an interactive map interface.
There are some pretty neat Silverlight mapping plugins that I think could work well, specifically:
ArcGIS Silverlight API: http://resources.esri.com/arcgisserver/apis/silverlight/
DeepEarth mapping framework: http://www.codeplex.com/deepearth
There are no doubt many more plugins out there that will allow easy interaction between ASP.NET and the mapping interface (please suggest some if I've missed the major players).
My major concern however is using these tools with local data sources. What is the best option here? All I need is some basic satellite imagery of moderate resolution and some overlays of cities and country borders. Can I download a dataset of these images? I dont really care if they are up to date or not, so long as the photos were taken in the last 20 years.
I want to be able to use local data sources because external internet connections could be very slow due to the nature of the organisation's work, Intranet communication will always be much faster.
To summarise:
1.) where can I find a dataset of moderate quality global satellite imagery?
2.) Which web based mapping plugin will allow me to plug into such a data source?
If I can get something like the DeepEarth demo (http://www.codeplex.com/deepearth) but grabbing the data from internal company servers I would be very happy.
You can check out the free geodata listing at:
- http://www.freegis.org/database/?cat=1
Or have a look at:
http://downloads.cloudmade.com/
where cloudmade provides downloadable openstreetmap data converted to shape files.
I'm building a little play project and I'd like to use satellite images of a town inside deepzoom, what's the easiest way to get them? I'm sure there's a MUCH better way than PrtScn, I've tried google maps downloader but it doesn't download satellite images and it's company don't seem to be offering it anymore.
Take a look at Deep Earth, unless what you're trying to build is what deep earth give you - in which case it may remove all the fun ;)
http://www.codeplex.com/deepearth
If you want to go your own way, then it used to be that you could just manually request the various image tiles directly from the MS Virtual Earth server hosting them, if you could calculate the quad keys and build the correct URL, thus bypassing their payment model. Whilst I know they were looking to cut out this loop hole, that's certainly what early versions of Deep Earth did.
Microsoft Virtual Earth has SOAP and AJAX-based services that you can use in your application. The service has a Staging and Production version. Using the Staging version is free, and could easily serve the needs of a "play project." The Production version costs money and can serve info to a large application with many users.

However there is some registration required to get working with the Staging sdk. You can get started here: http://msdn.microsoft.com/en-us/library/cc980844.aspx
