Efficient-VDSR Network for Super-Resolution
Xi Chen · Highlights in Science Engineering and Technology · 2022
Super-resolution image processing is an important research topic in the field of image processing. The exploration in this paper comes from the use of VDSR network, which can improve the learning rate by only detecting and learning the residuals since the difference between low-resolution and high-resolution images lies more in the high-frequency detail part. Increasing the depth of the network can significantly improve the learning rate and further affect the final rendering of the image, but the increase of weight layers also increases the number of iterations and training time. This paper intends to reduce the number of iterations by decreasing the number of weight layers and correspondingly shorten the training time of the model. Then, we create low-resolution images and improve the resolution of the images by using bicubic interpolation method and the trained network respectively, and then obtain the evaluation data of the image quality by final visualization and quantitative comparison. The results show that reducing the number of weight layers still leads to a high accuracy of the images and will reduce the number of iterations and time accordingly.
