I'm making a very basic Image Processing program in Java and I have a few pre-defined 3x3 matrices for various convolutions (sharpens, blurs, edge detections etc) I have them hard coded for now for testing purposes but am trying to put them in a more appropriate format like enum but I'm not sure how to use 2D arrays as enums. When I try to access the kernels indices I just get a warning that the expected type is array but resolved to kernel.
IDENTITY(new double[][] { {0, 0, 0}, {0, 1, 0}, {0, 0, 0} }), EDGE_DETECTION_1(new double[][] { {-1, -1, -1}, {-1, 8, -1}, {-1, -1, -1} }), EDGE_DETECTION_2(new double[][] { {1, 0, -1}, {0, 0, 0}, {-1, 0, 1} }),I'm a little new to using enums more complicated than basic Strings etc so I could be missing very obvious things but I would appreciate any pointers.
