HistLib is a C++ histogram visualization and manipulation library built with OpenCV. This library provides the ability to create custom histograms, generate histograms from grayscale/color images, and apply value channel normalization using a set of simple functions.

Please see Samples on how to use this library.

Input	Histogram

Version 0.3

• Switched to the CMake build system
• Refactored functions into an object oriented library
• Cleaner sample code
• Extensive commenting

Checkout or extract the source into `/code/opencv-histlib`

# Make a new build directory for the project
mkdir ~/code/build/opencv-histlib
cd ~/code/build/opencv-histlib

# Initialize the CMake build environment
cmake ~/code/opencv-histlib/

# Copy images to the build directory  (required to run the sample code)
cp -Rf ~/code/opencv-histlib/images ./

# Build and run the sample code
make
./sample

The output from sample should look like this:
