Frame Difference in gray scale
1. I applied cvMean on original gray scale image and set as thresold
So, result: http://imm.io/8x9p
2. then i get cvMean from the cvAbsDiff() ressult that set that mean value as
result : http://imm.io/8x9H
And, When ever i apply this cvAbsDiff() it gave me moving edges but i meed
moving hand instead of moving edges.
My code : http://codepad.org/ZsaeWeB4
probably , I have no concept that how to get moving hand using cvAbsDiff() ..
Every result in any color space give me moving edges .not moving hand .. .
This is the result after morphology operations for filling the interior of hand
. but in my point of view that is not possible . because morphology will only
apply where we have hand movement and hand movement only appears at edges in
form of shadow.
I do't understand how my friend said me that you have to fill the hand area ...
If i set rectangle on hand. then my rectangle on hand do't fit extacly because
during motion my edges breaked . so rectangle do't set directly on hand .
Please guide me that how can i get back my hand ???
ok well i did more dilate and erode
almost near to get hand . may be need more dilate and erode
but this is not good way to get hand . because more dilate and erode as a
result speed slow .
speed is too slow .Is there any other way to fill the interior of hand ?
Please tell me that is there any other way to get back my hand ??
