A Scene Text Detector for Text with Arbitrary Shapes

Abstract EN

The performance of text detection is crucial for the subsequent recognition task.

Currently, the accuracy of the text detector still needs further improvement, particularly those with irregular shapes in a complex environment.

We propose a pixel-wise method based on instance segmentation for scene text detection.

Specifically, a text instance is split into five components: a Text Skeleton and four Directional Pixel Regions, then restoring itself based on these elements and receiving supplementary information from other areas when one fails.

Besides, a Confidence Scoring Mechanism is designed to filter characters similar to text instances.

Experiments on several challenging benchmarks demonstrate that our method achieves state-of-the-art results in scene text detection with an F-measure of 84.6% on Total-Text and 86.3% on CTW1500.
