Using Matlab, implement the adaptive filter below. The noise variance will be used as one of the input variables. Read in a grayscale image. If you can, also try out this filter for an RGB image.

g(x,y) input image , N-Oise variance, you can specify in MATLAB m, Local mean within a window, i.e. 3x3 or 5x5 , Local variance within a window. 1.e. 3 x 3 or 5 x 5 g(x,y) input image , N-Oise variance, you can specify in MATLAB m, Local mean within a window, i.e. 3x3 or 5x5 , Local variance within a window. 1.e. 3 x 3 or 5 x 5
