Shape Robust Text Detection with Progressive Scale Expansion Network

7 Jun 2018Xiang LiWenhai WangWenbo HouRuo-Ze LiuTong LuJian Yang

The challenges of shape robust text detection lie in two aspects: 1) most existing quadrangular bounding box based detectors are difficult to locate texts with arbitrary shapes, which are hard to be enclosed perfectly in a rectangle; 2) most pixel-wise segmentation-based detectors may not separate the text instances that are very close to each other. To address these problems, we propose a novel Progressive Scale Expansion Network (PSENet), designed as a segmentation-based detector with multiple predictions for each text instance... (read more)
