In this work, I coded the Coherent Line Drawing filter using C++11 and OpenCV 3.1. See references and details in the presentation.pdf.
Simple run make cohelines. You need the OpenCV library to build and run. It was tested only with OpenCV 3.1. Also, it depends on pkg-config, make and g++ tools.
Run ./cohelines <image_path>. I didn't coded the tunning parameters input, so you need to rebuild for each change in the algorithm parameters (or build the input yourself :D).
