  1. Hello, I am having a bit of an issue applying a threshold to an image and getting reliable results. I am thinking using edge detection prior to doing any other image processing could make this work... but I am at a loss for how to implement it. If you look at the image below you will see the root of my problem. The top set of images and bottom are only a second or 2 apart but the threshold sees them differently, yet the edge detection seems to correctly detect the edges the same. I only care about the range of pixels that usually makes up the brightest part of the im
  2. I am trying to do hand gesture recognition for any background ( not by using a single color plane behind the hand ). I am acquiring the image by using the integrated webcam that is present in my laptop. once the gestures are identified , i need to take some decisions to control someother instrument. I am trying this by using image processing techniques like edge detection, template matching etc. I am not able to find expected results..Is there any precautions to be handled to get this correct ?
