Hello everyone I was trying to divide an image into N different blocks in the width after I performed this code to get its edge points:
Ioriginal = imread('sample.jpg') %read the image
Igray = rgb2gray(Ioriginal) %change it to gray scale
InoNoise = wiener2(Igray) %remove noise from image
image = edge(InoNoise, 'prewitt') %get the edge points of the image
the result is shown in this picture

Now what i want to do is dividing the image into N equal blocks and calculate the edge points of each block
I really appreciate if someone can really help me doing this part
Thank you
