Adaptive Multi-Scale HyperNet with Bi-Direction Residual Attention Module for Scene Text Detection

Abstract

Scene text detection is an important step in the scene text reading system. There are still two problems during the existing text detection methods: (1) The small receptive of the convolutional layer in text detection is not sufficiently sensitive to the target area in the image; (2) The deep receptive of the convolutional layer in text detection lose a lot of spatial feature information. Therefore, detecting scene text remains a challenging issue. In this work, we design an effective text detector named Adaptive Multi-Scale HyperNet (AMSHN) to improve texts detection performance. Specifically, AMSHN enhances the sensitivity of target semantics in shallow features with a new attention mechanism to strengthen the region of interest in the image and weaken the region of no interest. In addition, it reduces the loss of spatial feature by fusing features on multiple paths, which significantly improves the detection performance of text. Experimental results on the Robust Reading Challenge on Reading Chinese Text on Signboard (ReCTS) dataset show that the proposed method has achieved the state-of-the-art results, which proves the ability of our detector on both particularity and universality applications.
