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.

Multi-View Constraint Propagation with Consensus Prior Knowledge

no code implementations21 Sep 2016 Yaoyi Li, Hongtao Lu

In this paper, we present a method dubbed Consensus Prior Constraint Propagation (CPCP), which can provide the prior knowledge of the robustness of each data instance and its neighborhood.

Adaptive Affinity Matrix for Unsupervised Metric Learning

no code implementations13 Nov 2015 Yaoyi Li, Junxuan Chen, Hongtao Lu

In this paper, we propose a novel method, dubbed Adaptive Affinity Matrix (AdaAM), to learn an adaptive affinity matrix and derive a distance metric from the affinity.
