Augmented lazy snapping: how does pre-segmentation help lazy snapping framework?

Autor: Dong-sun Seo, Trung Hieu Tu, Tran Hoang Nam

Publikováno v: Ninth International Conference on Graphic and Image Processing (ICGIP 2017).

We present Augmented Lazy Snapping, an interactive image segmentation algorithm. We investigate the presegmentation step in the Lazy Snapping method and find the method can be improved by changing the middle layer of segmentation pipeline. To be more
