Revisiting Shadow Detection from a Vision-Language Perspective
Yonghui Wang, Shaokai Liu, Wengang Zhou +2
Shadow detection is commonly formulated as a vision-driven dense prediction problem, where models rely primarily on pixel-wise visual supervision to distinguish shadows from non-sh…
BookNet: Book Image Rectification via Cross-Page Attention Network
Shaokai Liu, Hao Feng, Bozhi Luan +3
Book image rectification presents unique challenges due to its complex geometric distortions from binding constraints, where left and right pages exhibit distinctly asymmetric curv…
RoFIR: Robust Fisheye Image Rectification Framework Impervious to Optical Center Deviation
Zhaokang Liao, Hao Feng, Shaokai Liu +2
Fisheye images are categorized fisheye into central and deviated based on the optical center position. Existing rectification methods are limited to central fisheye images, while t…
DeepEraser: Deep Iterative Context Mining for Generic Text Eraser
Hao Feng, Wendi Wang, Shaokai Liu +3
In this work, we present DeepEraser, an effective deep network for generic text removal. DeepEraser utilizes a recurrent architecture that erases the text in an image via iterative…
