猫脸变换用于水印中，将水印图像经过一定次数的变换得到不能识别的图像，增强了水印的鲁棒性(Cat face transform for watermarking, the watermark image after a certain number of times the transform of the image does not recognize and enhance the robustness)

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.
