Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0036] The present invention proposes a method for realizing face super-resolution based on learning multi-view texture compensation. The face image super-resolution method uses multi-view texture compensation to combine two face images to generate a high-resolution image as an output. Use the texture attention mechanism to transfer high-precision texture compensation information to the fixed vi...

Abstract

The invention discloses a face super-resolution method and device based on multi-view texture learning. The method belongs to the field of human face image super-resolution, and comprises the following steps: firstly, down-sampling a high-resolution human face image pair to a target low-resolution human face image pair, carrying out blocking operation on the target low-resolution human face imagepair, separating out mutually overlapped image blocks, and extracting facial texture multi-scale features by using a residual pooling module network; then, the extracted face multi-scale features aresent to a texture attention module, texture information is fused and compensated by calculating an attention map, the most similar features are collected, and the SR performance is more effectively improved. Finally, a feature map of the target view image is updated by feature fusion to produce a high resolution result. The network provided by the invention is superior to other latest face image super-resolution algorithms, and a face image with higher quality can be generated.

Description

technical field [0001] The invention belongs to the field of super-resolution of human face images, and more specifically relates to a method and device for super-resolution of human faces based on multi-view texture learning. Background technique [0002] Face super-resolution (super resolution, SR) can reconstruct a high-resolution (High Resolution, HR) image from one or more low-resolution (Low Resolution, LR) input images. Due to its excellent ability to reconstruct image details, face SR is widely used in video surveillance, face recognition, entertainment, etc. Generally, face image super-resolution methods include three typical methods: interpolation-based, reconstruction-based and learning-based methods. Because the learning-based face super-resolution method utilizes additional prior knowledge from training samples to achieve the reconstruction task. Therefore, learning-based face image super-resolution has become more and more popular in recent years. [0003] A...
