Farrahi Moghaddam and M. Cheriet, A multi-scale framework for adaptive binarization of degraded document images, Pattern Recognition, 43, pp. 2186--2198, 2010, DOI: 10.1016/j.patcog.2009.12.024USAGE:ugray0 = universal_color_to_gray_converter(u, method_flag, method_name);where u is the input color image. method_flag is 'method' method_name is one of above mentioned methods. ugray0 is the output gray-level image.ORugray0 = universal_color_to_gray_converter(u);where u is the input color image. ugray0 is the output gray-level image; in this case, the method is 'min_avg';
