Overview
A manual 2D convolution and correlation implementation with stride and padding options, applied with edge, blur, and sharpen kernels and checked against scipy.signal.convolve2d.
Interactive demo
Stride, valid or same padding, and convolution versus correlation, as in the notebook. The Sobel and Prewitt presets use the standard kernels.
