I recently was reviewing ImageCorners.jl and it uses imgradient a lot, and there exist of lot of different types of filter like prewitt, sobel etc that are utilized. I would wanna introduce readers to:
gradient in general
gradient for a 2d signal, (grad_x, grad_y)
gradient orientation and magnitude and help visualize
gradient operator([grad_x, grad_y]) this is going to be useful later I know
