You are interested in a particular area or specific line?
The question seems not so difficult, @ImageAnalyst or other MVPs can answer it more perfectly.

Have a look bwlabel and regionprops. With these functions you can find the area of each closed region. The broken region will have large area compared to others.

The purpose is to find all the holes on the image.My thinking was to detect the holes from the Area using bwlabel and regionprop. The problem is that it detects also texel 60 which is not a hole but it's quite big to be detected. The texel 366 which is a hole has less Area than #60. So the Area is not a unique condition to to distinguish a hole from a texel
