Is there any way to detect horizontal and vertical edges ?

I have divided the digit image into 6 blocks. Now, I need to detect whether there is horizontal or vertical or both edges in each of the block. The block image is attached.

There are the numbers of ways, it depends on what result you are looking for.

Check here imgradient or Directional gradients of an image (function imgradient )

If you check in Gonzalez book there also mentioned the H and V edge detection (Image Segmentation Chapter)

I need to return Boolean (1) if exists either one. Is it possible using imgradient?
