Subtract & get difference of two images(touchpaint) and get an integer value in Android
<p>I have a requirement where the user needs to draw something on a FingerPaint like application and submits. I need to check to what extent the image matches and take the difference of the user's image with the ACTUAL image. The difference should then return an integer value. Depending on that, the user gets a score. Any suggestions is it possible to take difference of two images just like in MATLAB in Android?</p>
