Write a small piece of pseudo-code for generating a histogram H[L] for an intensity image I[YDIM][XDIM], where L is the total level of intensities of the image, H is the histogram array, XDIM * YDIM are the size of the image, and I[i][j] is the intensity value of the pixel at location (i,j), with i = 1, ..., YDIM, and j = 1,..., XDIM. You might choose to use a certain program language that you are familiar with to write the code. You don't have to compile the code.
