The most sucessfull single stage object detection algorithms, e.g., YOLO, SSD, all relies all some anchor to refine to the final detection location. For those algorithms, the anchor are typically defined as the grid on the image coordinates at all possible locations, with different scale and aspect ratio.

In this post, we will introduce some of the most recent text detection methods. Text detection methods are highly related to object detection methods, thus could be categorized into one-stage methods and two-stage methods. Currently, two-stage methods could easily outperforms one-stage methods, e.g., using Mask-RCNN directly could give you 76% mAP on icdar2017mlt, while the current state of art methods psenet achieves 72%.
