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.
