Alphamatting is the problem of extracting the foreground from an image. Given the input of an image and its corresponding trimap, we try to extract the foreground from the background.
|
||
|
||
This project is implementation of "[Designing Effective Inter-Pixel Information Flow for Natural Image Matting](https://www.researchgate.net/publication/318489370_Designing_Effective_Inter-Pixel_Information_Flow_for_Natural_Image_Matting)" by Yağız Aksoy, Tunç Ozan Aydın and Marc Pollefeys[1]. It required implementation of parts of other papers [2,3,4].
