A grayscale image is represented as a matrix in MATLAB. Each matrix element represents a pixel in the image. The element values represent intensities of the pixel at that location.
Given an input image matrix I, return a cropped image matrix Icrop using the following additional inputs:
For example, if your image was:
I = [1 2 3 4 5 6 7 8]
And you called crop_image with inputs
Icrop = crop_image(I, 2, 2, 1, 3)
The output should be
[6 7 8]
