Hi all. I am trying to use the dataset from this paper and segment hand from the image. I attach a sample RGB and depth image. I have written this code.
threshold=min_v+100;%threshold - varying this is not helping much but ofcourse will deteriorate
figure; imshow(BW);%shown in result3.jpg file.
The result is shown in the result3,jpg file which is attached. As you can see even elbow comes. How do I segment just the hand? I am relatively new to RGB and depth images and kinect. Any help is greatly appreciated.

Hey! can you give the dataset as the link that you mentioned above for dataset is not working/showing error.

If the person always has a black wrist band, then you should have 2 blobs, not 1, and then you can use bwareafilt() to extract the largest one, which will be the forearm, and then subtract that from the original mask to get only the hand.
forearmMask = bwareafilt(binaryImage, 1);
handMask = binaryImage & ~forearmMask;
