Abstract

The embodiment of the invention discloses an image processing method for super-resolution reconstruction. The image processing method is characterized in that the image processing method includes the following steps: a clip of sequential images, which includes at least two frames of images, is acquired; on the basis of an invariant-feature automatic registration algorithm, the sequential images are registered; the registered images are calculated by mixed interpolation and mapped onto a preset target resolution grid, and by means of holes produced after template convolution filling and mapping, a hole-filled image with target resolution is outputted; the image with target resolution is denoised and deblurred, and a processed target resolution image is outputted. The adoption of the invention can realize real-time super-resolution reconstruction, thus solving the inherent defects of the super-resolution reconstruction method in the prior art that: the speed is not high enough, the quality of reconstruction is not good enough, and under the premise of guaranteeing the quality of reconstruction, real-timeness is hard to guarantee.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and system for super-resolution reconstruction. Background technique [0002] Super-resolution reconstruction is to reconstruct one or more low-resolution observation images into a high-resolution image, which can improve the quality of the image, essentially enhance the resolution of the image, and make the reconstructed image more accurate than the original image. clear. The current super-resolution inventions all have defects such as large amount of calculation, or unsatisfactory effects. [0003] The patent application number CN201010518352.8 provides a super-resolution reconstruction based on frequency-domain registration and convex set projection. This method first reads in multiple frames of images, and selects one as a reference frame for registration, and then The images are registered to obtain the relative displacement of each frame ...
