+ * This module is dedicated to compute alpha matting of images, given the input image and an input trimap.
+ * The samples directory includes easy examples of how to use the module.
+ *
+ * The implementation is based on Designing Effective Inter-Pixel Information Flow for Natural Image Matting by Yağız Aksoy, Tunç Ozan Aydın and Marc Pollefeys, CVPR 2019.
+ *
+ * This module has been originally developed by Muskaan Kularia and Sunita Nayak as a project
+ * for Google Summer of Code 2019 (GSoC 19).
