Abstract
Systems and methods for enhancing text in images based on super-resolution are disclosed. A low resolution image is generated based on a high resolution image. A super resolution image is generated based on the low resolution image, using a super resolution model with a set of parameters. Based on the high resolution image and the super resolution image, a total loss function is computed based on: the set of parameters, a detection loss function, a recognition loss function, and a gradient loss function of the high resolution image and the super resolution image. A trained super resolution model is generated with an optimized set of the parameters that minimizes the total loss function. Text in at least one image is enhanced using the trained super resolution model.
