In this research, we propose a loss function for WDSR (Wide Activation Super Resolution) model to enhance the edge of target object. In the design of our proposed loss function, in addition to the basic pixel error, we take other criteria including edges, features and residuals in edges regions into account. Edges are the fundamental structures of the image. Feature map is the element that capture the main characteristics of the images. And the residuals on edges can affect the visualization of the image. With the combination of the three items and basic pixel loss, in the end of our experiment, we manage to enhance the edge portion of the images.
