Description

technical field [0001] The invention relates to the field of image processing, in particular to an image clarity detection device through plaque feature registration. Background technique [0002] Image registration is the process of spatially aligning two or more images of the same scene taken at different times, from different viewpoints, or with different sensors. Its main purpose is to eliminate the geometric deformation caused by different imaging conditions between the reference image and the image to be registered, so that the two have spatial consistency. Image registration algorithms in the prior art can reduce the uncertainty of scene understanding by enhancing the complementarity between information. In the process of image registration, due to the large visual difference in the imaging results of the same scene, it brings great difficulties to the registration, and the existing registration algorithms are not good in terms of accuracy, efficiency, stability and ...
