% LeDecolor - Log-Euclidean Metrics for Contrast Preserving Decolorization
% gIm = LeDecolor_v1(Im, gamma) performs contrast preserving decolorization
% on color image Im, with controling parameter gamma
%
% Paras:
% @Im : Input image (double), only color images are acceptable.
% @gamma : Controlling parameter defined in [1]. 0.2 by default.
%
% Example
% ==========
% Im = im2double(imread('6.png'));
% gIm = LeDecolor_v1(Im); % Default Parameters (gamma = 0.2)
% figure, imshow(Im,[]), figure, imshow(gIm,[]);
