This damned question. Help please.

(15%) 8. Suppose that you have a grayscale image where the pixel values are in the range 0- 255 where O is black and 255 is white. Someone has marked up the image with white plus signs indicating points of interest in the image. The plus signs are 3 x 3arrays with the values: 0 255 0 255 255 255 0 255 0 You want to count the number of plus signs that appear in the image matrix. For example, there are 3 plus signs in the following image matrix: 5 6 4 1 290 255 0 0 255 03 74255 255 255 255 255 215 4 5 7 0 255 0 0 255 10 7 9 255 255 255 7 9 6 6 4 7 0 255 0 9 1 5 0 255 07 3 8 Complete the following MATLAB function (you can edit the function that is provided to you): function n count Pluses ( COUNTPLUSEs counts the number of plus sign patterns n countPluse s (A) returns the number of times 8 the pattern: 0 255 255 255 255 0 0 255 appears in a matrix A. It is assumed that there % are no overlapping plus sign patterns in A. You may use the MATLAB functions all, any, and any function that determines the size of a matrix, but do not use any other MATLAB functions in your solution
