function q = imagequant(x, w1, w2, w3)
|
||
|
|
%imagequant quantizes the pixel values of a tri-chromatic image
|
||
|
|
% Usage q = imagequant(x, w1, w2, w3), where:
|
||
|
|
% Inputs
|
||
|
|
% - x is the input image who's values are going to be quantized
|
||
|
|
% - w1 is the quantization step size for the first channel (red)
|
||
|
|
% - w2 is the quantization step size for the second channel (green)
|
||
|
|
% - w3 is the quantization step size for the third channel (blue)
|
||
|
|
%
|
||
|
|
% Output
|
||
|
|
% - q is the image with the quantized values
