HI friends...I am going to develop Windows phone 8 app (Xaml/C#) which can identify signs (Like famous Logos) using camera. It is like capturing QR code using windows phone. As an example through my application I can scan (like QR code) and identify the Logo which appears in somewhere in board or a picture etc... (Think I have database which is filled with logo information (logo pictures an info) and I connected it to windows phone app.)So my questions are What are the image processing SDKs and libraries I can use to develop this app ?Is there any Blog post which describes those things?Any sample codes?
Thank you very much in Advance
This is a library which has proven to work on WP7 so i'm guessing it will work on WP8 aswell.
It main purpose was augmented reality but its a "vision" library which means you can probably do loads of other vision commands (labelblobs, invert colors etc..)
Link to the library: Here
Samples of its use: Here

I'm implementing WPF app where I need to take high quality photos from integrated camera. So far I've been successful with capturing video and taking frames from it (described for example here: Wpf and C # capture webcam and network cameras).
But this is not what I want - because video frame quality is not so great. I have MS Surface 4 Pro which has 8Mpx camera with full HD video support and with the above method I'm able to just get full HD frame from it. But I would like to have full 8Mpx picture, like it is possible to take in the native Windows Camera app.
In UWP I would probably have been successful with CameraCaptureUI class, but I didn't find any clues for WPF.
Does anyone has an idea how this could be implemented?
I've found out that XAML Islands do work with .NET Framework 4.8. So I've been able to implement a WPF solution using UWP components MediaCapture and CaptureElement. With that I can take photos with full resolution which was my goal.
Simple sample project can be found here: https://github.com/ondrasvoboda/WPFCamera, consider it just as a proof of concept.
If your app will run on Windows 10 or above, you can now use most of the APIs from Windows 10 in a WPF application.

I am making a .net web app. My attempt of taking a picture and trying to extract text from that picture has a terrible success rate. I see apps that let you scan a page into pdf. I want to use that approach using the users phone camera. I need help identifying the best free APIs that will help accomplish this.
I don't have any code yet; I don't want you to do it for me rather just help me find the resource. I'm new to this and here to learn and get educated.
The most popular open source ocr solution is Tesseract.
Here are 2 github links to Android and IOS open source solutions using Tesseract:

I have a Desktop Based piece of Touch Screen Software. As part of the process you capture a photo of the user to store later on. The Application works perfectly fine in all versions of Windows other than Windows 8.1 on a Surface Pro 3 (seems to be machines with Metro on).
When it comes to Windows 8.1 the Application Captures the image with no issues. When you then go back to the page to capture again it is unable to grab the camera to take another photo?
Using the Camera Capture in Windows 8.1 itself uses the camera with no issues again. Restarting the Surface Pro allows the camera to work in the application again for one instance and then stops again.
I've tried scouring the web but not having much luck so far. We're using the DirectShow lib
Any advice/ideas/help would be greatly appreciated.
Thanks

I`m trying to make an windows phone 8 app which simply allow you to click a button which result in start recording and showing any visualization that indicate that its recording something like a bar or a vu meter , I managed to make the recording part, now i dont know what type of projects i should use to support making such visualization.
does Windows phone 8 apps support using XNA to draw in a box inside a xaml file ?
what is the tag i can use to draw inside using XNA code ?
If you're targeting WP8 you can't use the hybrid SL/XNA model. That said, you can certainly use a Hybrid solution that draws using DirectX. You can find general information here and a sample here (note that it uses DrawingSurfaceBackgroundGrid, you probably want DrawingSurface).

It looks like MSDN has a number of articles that should help you on your way:
Adapt Your App (vague overview)
Adaptable Apps For Windows Mobile explains various techniques for supporting dynamic screens
The Mobile Client Software Factory provides a pattern for helping with dynamic screens
Finally, Windows Marketplace for Mobile: Certification Testing, Hopper, and Multiple Screen Support provides some fairly up to date information on the certificate requirements for the WM6 marketplace as they relate to dynamic screens.
