We have to create an android application in OpenCV to detect human upper half body i.e shirt detection. We need to get the structure of the shirt exactly with the edges.

We are beginners to opencv.. please help us on the same

you could read about segmentation methods, like watershed or grabcut

The code below should give you the correct output:

blur = cv2.blur(img,(9,9))
blur2 = cv2.GaussianBlur(img,(3,3),0) 
absd=cv2.equalizeHist(cv2.cvtColor(cv2.absdiff(blur2,blur),cv2.COLOR_BGR2GRAY))

Good luck!

This will sharpen the edges, but it will not give you the shirt only. I guess you would want to combine this with an upper body detector and a watershed based algorithm on top of your generated edge map.
