Logic i thought is, first search for pixel having zero intensity value and then find its neighbor pixels by traversing and increase count whenever pixel with zero intensity occurs and then change the color of that pixel. After getting length of one line with same procedure find the length of other two. But i am not getting how to put it in code. Please can you help me in coding this or any other method is also fine.
Thank u

Try improfile(). Or just get a line of pixels and use find(). Or use regionprops() to find 2-D bars and get their length that way.
