Can anyone help in how to join the discontinuous boundary of this image. And how to fill inside this boundary. the image is obtained using 'Sobel edge detector in Matlab'.

Sobel is probably not good, or not enough. If it's a video of a person walking, try optical flow. Why do you think edge detection is the best approach?
