Problems solved by technology

[0002] In surveillance video, due to the quality of the camera itself or the influence of ambient light, the target in the image is often not clear enough. If the target is a moving object, there may be motion blur, even if the image is extracted frame by frame. , it is also difficult to get a clear target

Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] figure 1 Shown is the flowchart of the fuzzy image recovery method provided according to a preferred embodiment of the present invention, including the following steps:

[0023] In step 102, a blurred image block is determined in the selected frame image;

[0024] In step 104, the candidate blocks matching the blurred image block are respectively obtained in the multi-frame reference image, wherein the multi-frame reference image and the selected frame image form a continuous multi-frame image;

[0025] In step 106, a clear image block corresponding to the blurred image block is generated according to the plurality of candidate blocks and the blurred image block.

[0026] For example, if 5 ...

Abstract

The present invention provides a blurred image restoration method and system. The method comprises following steps: determining a blurred image block in a selected frame of image; respectively acquiring a candidate block matching with the blurred image block from multiple frames of reference image, wherein the multiple frames of reference image and the selected frame of image constitute a continuous multi-frame image; and generating a clear image block corresponding to the blurred image block according to a plurality of the candidate blocks and the blurred image block. The technical solution of the present invention can restore a blurred image to obtain a clear image.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a blurred image restoration method and system. Background technique [0002] In surveillance video, due to the quality of the camera itself or the influence of ambient light, the target in the image is often not clear enough. If the target is a moving object, there may be motion blur, even if the image is extracted frame by frame. , and it is difficult to get a clear target. In the image restoration technology, some classic common image restoration algorithms have been formed, such as unconstrained least squares method, constrained least squares method, inverse filter, Wiener filter, maximum entropy restoration method, etc. A new fuzzy image recovery technology is needed, which can also obtain clear images and enrich image recovery methods. Contents of the invention [0003] The present invention provides a blurred image restoration method and system to solve the above problem...
