Description: A document Text Localization Generative Adversarial Nets (TLGAN) model is utilized to perform the text localization task using SROIE data set. TLGAN learns text-image features via ImageNet pre-trained VGG network in adversarial manner and points out text locations. Note the images were scaled in an arbitrary ratio and the detected coordinates were re-scaled into original image space for the submission.

Description: Our model trained PANNet and multi oriented corner text detectors, and ensemble multi-scale images detection results. Besides, we pre-process the training and testing images to make them clear. Multi-scale training, training data augment are used.
