Hi, I am trying to extract a part of an image to get average pixel intensity of that part.
Attached image '1.jpg' is the original image and '1.. line.jpg' shows the part that I want to extract.
I cannot use the imcrop command since the part I want is not rectangular.
I tried using the drawpolygon command and got the vertices of the polygon, but I couldn't take it any further.
Can anybody help me?
Thank you in advance.
