Embodiment Construction

[0087] In order to have a further understanding and understanding of the structural features and the achieved effects of the present invention, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0088] Such as figure 1 As shown, a kind of self-adaptive image repairing method based on continued fraction interpolation technique described in the present invention can obtain the initial repaired image through unary continued fraction interpolation, and then carry out the initial repaired image through binary continued fraction interpolation Patch again to get the final patched effect. In the present invention, the combination of the two methods will not bring about the problem of a huge amount of calculation, because the calculation amount of the simple unary continued fraction interpolation repair is much smaller than that of the simple binary continued fraction interpolation repair, so the unary continuous fraction The fracti...

Abstract

The present invention relates to an adaptive image inpainting method based on a continued fraction interpolation technology and a system thereof. Compared to the prior art, the defects of bad inpainting effect and low efficiency are solved. The method comprises the following steps: initialing image characteristic analysis; employing a unitary continued fraction interpolation technology to perform inpainting of damaged points of a scratched image; employing a binary continued fraction interpolation technology to perform inpainting again of the scratched image, taking an initial inpainting image A as an information image, determining the position of each damaged point through a mask artwork, employing the binary continued fraction interpolation to update pixel information around the damaged points to obtain pixel information of each damaged point, and obtaining a final inpainting image B. The adaptive image inpainting method based on the continued fraction interpolation technology and the system thereof improve the quality and efficiency of image inpainting, can perform inpainting of any types of scratches, and are suitable for processing of all the images.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an adaptive image repair method and system based on continued fraction interpolation technology. Background technique [0002] Image restoration is to repair the damaged part of the image in a certain way to make it a complete image. Image restoration has a wide range of applications in image processing, film industry and other industries, such as the removal of scratches in photos and old movies, the removal of text and occlusions in images, etc. are all related to image restoration. Therefore, image inpainting has great application prospects and is a research hotspot in computer vision and computer graphics. [0003] At this stage, many researchers have proposed different image inpainting methods, and have achieved some success, but these methods lack versatility, incomplete inpainting, and blurred boundaries at the same time. Among them, methods based on partial dif...
