OpenCV-Entropy

histGray.cpp is used to calculate the entropy of a grayscale image histColor.cpp is used to calculate the entropy of color image, the color image is first split into YCbCr and then the histogram and entropy is calculated per each channel myHist.cpp is used to calculate the entropy of a grayscale image without using OpenCV's calcHist

to compile use: g++ -ggdb pkg-config --cflags opencv -o histGray histGray.cpp pkg-config --libs opencv or use 'buildme.sh' ./buildme.sh histGray.cpp
