function hsi = rgb2hsi(rgb)%RGB2HSI Converts an RGB image to HSI.%   HSI = RGB2HSI(RGB) converts an RGB image to HSI. The input image%   is assumed to be of size M-by-N-by-3, where the third dimension%   accounts for three image planes: red, green, and blue, in that%   order. If all RGB component images are equal, the HSI conversion%   is undefined. The input image can be of class double (with values%   in the range [0, 1]), uint8, or uint16. %%   The output image, HSI, is of class double, where:%     hsi(:, :, 1) = hue image normalized to the range [0, 1] by%                    dividing all angle values by 2*pi. %     hsi(:, :, 2) = saturation image, in the range [0, 1].%     hsi(:, :, 3) = intensity image, in the range [0, 1].%   Copyright 2002-2004 R.
