Abstract
Extracting textual information embodied in natural scenes is a very challenge task, and has a great influence on the performance of the following text recognition and understanding. It can be seen as an image-to-image conversion task, in which we transform the front text in each natural image into a specified color and the background into black. After that, we use the connected component algorithm to extract text from the two-color image. Based on such motivation, we proposed an approach based on generative adversarial learning to deal with the image-to-image conversion. The neural network in our approach consists of a generator sub-network and a discriminator sub-network, which are trained with paired images (scene images and their corresponding two-color images) in an adversarial way. After the training stage, the generator network is used to perform image conversion. Experiments on standard datasets including KAIST scene text database and MSRA text detection 500 database demonstrate that the proposed algorithm achieves a very competitive performance.
