Turn the neighborhood of a pixel into a set of bands. The neighborhood is specified using a Kernel, and only non-zero-weight kernel values are used. The weights of the kernel is otherwise ignored.
Each input band produces x * y output bands. Each output band is named 'input_x_y' where x and y indicate the pixel's location in the kernel. For example, a 3x3 kernel operating on a 2-band image produces 18 output bands.
