Example Embodiment

[0052] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0053] like figure 1 As shown, a method for repairing a damaged image includes the following steps:

[0054] Step 1, input a damaged image;

[0055] Step 2, using a Gaussian filtering method to remove background noise in the damaged image;

[0056] Step 3, using the threshold segmentation method to binarize the enhanced image;

[0057] Step 4, using the edge detection method to obtain the outline of the damaged image, and looking for an area in the undamaged area that is the same size and shape as the damaged area as the area to be matched;

[0058] The step 4 is specifically:

[0059] Step 4.1, obtaining the outline of the damaged image, selecting a pixel on the outline, and establishing a repair window with th...

Abstract

The invention relates to a method and a system for restoring a damaged image. The method includes following steps: inputting a damaged image; removing background noises by employing a Gaussian filtering method; performing binarization processing of the enhanced image by employing a threshold segmentation method; obtaining the contour of the damaged image by employing an edge detection method, searching an area whose size and shape are the same with the size and the shape of a damaged area in a non-damaged area, and regarding the area as a to-be-matched area; duplicating the pixel value of the to-be-matched area to the damaged area; and performing enhancement processing of the restored image by respectively employing top-hat transform and bottom-hat transform, performing smooth processing of the enhanced image by employing a bilateral filtering method, and accomplishing the restoration. According to the method and the system, the restoration effect is good.

Description

technical field [0001] The invention relates to the field of image repair, in particular to a method and system for repairing damaged images. Background technique [0002] Image restoration refers to the restoration and reconstruction of damaged images or the removal of redundant objects in images. At present, image restoration methods include the following: Partial differential equation method: In this method, the user needs to specify the area to be repaired, and the algorithm diffuses the information outside the contour line of the boundary of the area to be repaired to the middle area to be repaired along the contour normal direction. on the pixel. The algorithm uses the smoothness of the local color to diffuse along the contour line, and considers the anisotropic diffusion to ensure the continuous boundary at the edge, but the calculation of this method is unstable. Overall variational method and curvature-based diffusion model: it uses the Euler-Lagrange equation and...
