Super-resolution single image construction method and device

The invention provides a super-resolution single image construction method and device. The super-resolution single image construction method comprises the steps of S1, performing detail enhancement on an image edge part; s2, performing detail supplementation and enhancement on the non-edge part of the image by using a single-image self-learning algorithm; and S3, image fusion enhancement: carrying out image weighted stacking, filtering and denoising on the images output in the step S1 and the step S2 to obtain a finally output high-resolution image. The image display effect is effectively enhanced, and the visual experience of a user is optimized. 本发明提供了一种超分辨率单图像构建方法及设备，包括：S1、针对图像边缘部分进行细节增强；S2、用单图像自学习算法针对图像非边缘部分进行细节补充和增强；S3、图像融合增强，对步骤S1和步骤S2输出的图像，进行图像加权叠加、滤波去噪，得到最终输出的高分辨率图像。本发明有效增强图像显示效果，优化了用户视觉体验。
