I am creating an 8-bit image with non-overlapping rectangles.
I'm using I=ones(256,256) to create a matrix with all 1's.
Now I have to create random rectangles inside the image such that they do not overlap.
My Idea is: First create a random rectangle by I(x:x+length,y:y+length)=0; then start a loop which checks whether the new x and y have pixel value 0. If it is 0 it means that the new rectangle is starting inside my previous rectangle. If not, it will create new rectangles until the loop terminates.
Note: I need algorithm not code as I am learning how to code in Matlab.
I am using randi to generate x and y : x=randi( [1,255] ,1)

Use inpolygon() to check if point is in rectangle
