You can convolve with the Laplacian, which is like the average edge over all 4 directions (vertical, horizontal, and the two diagonals).
kernel = [-1, -1, -1; -1, 8, -1; -1, -1, -1];
highPassFilteredImage = conv2(double(originalGrayImage), kernel, 'same');

its good its result in matrix, so if i need a value then what i should do, and if i want to count the edges then what is the procedure. Actually i need to count the edges in a sub image then categories the edges in 5 types, i-e. non directional, vertical , horizontal , and both diagonals, please help me out.
