This website helps generate a nonogram from an input image. The process is divided into three stages:
Convolution - Create and edit kernels to convolve with the image. Kernels are convolved in the order they appear in the list, top to bototm.
Downsampling - Select how many pixels the output image should be.
Color Quantization - Select what kind of nonogram (black/white or color) and how many colors should be in the palatte.
