Embodiment

[0021] In order to solve technical problems such as the ringing effect existing in existing blur restoration methods, an embodiment of the present invention provides a restoration method for blurred images, which is applied to blurred images generated due to the relative motion of the camera and the object to be photographed. The method includes The following steps:

[0022] Obtaining a smooth region of the image through the image;

[0023] Computing a smooth region labeling matrix through the smooth regions of the image;

[0024] generating an initial blur kernel from said image;

[0025] Obtaining an estimated value of the blur kernel by optimizing the initial blur kernel;

[0026] The blurred image is restored by the estimated value of the blur kernel.

[0027] The concrete realization process of the present invention is as figure 1 As shown, the specific implementation details of each part are as follows:

[0028] 1. Obtain the smooth area of ​​the image by the image ...

Abstract

The invention discloses a blurred image restoration method which is applied to the blurred images formed by relative movement of cameras and photographed objects. The method comprises the following steps: obtaining a smooth area of a blurred image through the image; calculating a smooth area marking matrix through the smooth area of the image; generating an initial blurred core according to the image; optimizing the initial blurred core to obtain an estimated value of the blurred core; and restoring the blurred image through the estimated value of the blurred core. According to the method, the smooth areas of the images are marked, and the smooth area information in the images are fully utilized to restrict the blurred core estimation process, so that the correctness of the blurred core estimation can be ensured; and the estimated blurred cores are utilized to restore the blurred images, so that significance is brought to the restoration of the blurred movement images.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a blurred image restoration method. Background technique [0002] When acquiring an image of a target, if there is relative motion between the target and the camera during camera exposure, it tends to blur the resulting photo. This image blurring is called motion blur. Therefore, in order to obtain more effective information in the image, analyze and process the image, it is necessary to perform clear processing on the image, that is, image restoration. Image restoration, also known as image restoration, refers to the removal or mitigation of image degradation that occurs during the acquisition of digital images. The purpose of image restoration is to restore the degraded image to its original real appearance as much as possible. The method is to start with the analysis of the mechanism of image degradation, that is, use a mathematical model to describe the image degrad...
