Text Detection

Description

CRAFT: Character-Region Awareness For Text detection, is designed with a convolutional neural network producing the character region score and affinity score. The region score is used to localize individual characters in the image, and the affinity score is used to group each character into a single instance. To compensate for the lack of character-level annotations, we propose a weaklysupervised learning framework that estimates characterlevel ground truths in existing real word-level datasets.
