Natural Image Matting via Guided Contextual Attention

1 code implementation13 Jan 2020 Yaoyi Li, Hongtao Lu

Inspired by affinity-based method and the successes of contextual attention in inpainting, we develop a novel end-to-end approach for natural image matting with a guided contextual attention module, which is specifically designed for image matting.

Trimap-guided Feature Mining and Fusion Network for Natural Image Matting

1 code implementation1 Dec 2021 Weihao Jiang, Dongdong Yu, Zhaozhi Xie, Yaoyi Li, Zehuan Yuan, Hongtao Lu

For emerging content-based feature fusion, most existing matting methods only focus on local features which lack the guidance of a global feature with strong semantic information related to the interesting object.
