Embodiment Construction

[0101] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0102] like figure 1 As shown in the present invention, a method for repairing positive and negative bank notes based on continued fraction interpolation technology can effectively restore damaged images through positive interpolation windows and binary vector rational interpolation, and then Another restored image can be obtained through the negative interpolation window and binary vector rational interpolation, and then the two images are optimized by weighting to obtain the final repair effect.

[0103] The interpolation window construction is used to reconstruct the pixel information of the damaged point, and the pixel information of the damaged point constructed by different interpolation windows will also have certain differenc...

Abstract

The invention relates to a damaged bank note image positive and negative repair method and a damaged bank note image positive and negative repair system based on a continued fraction interpolation technology. Compared with the prior art, the defect that the image repair technology lacks of stability and universality and cannot be used to repair image details is solved. The method comprises the following steps: making an initial image feature analysis; repairing the damaged points of a note image using a positive repair way; repairing the damaged points of the note image using a negative repair way; and constructing a final repair result C using the two repaired images. The quality and efficiency of image repair are improved.

Description

technical field [0001] The invention relates to the technical field of image restoration, in particular to a method and system for repairing positive and negative images of bank damaged bills based on continuous fraction interpolation technology. Background technique [0002] Image inpainting is to restore the integrity of the damaged image. It is to fill the specified area with information, so that the transition between the filled area and the original area is natural, and it looks like it has never been damaged. As an important part of digital image processing technology, image inpainting technology has great application prospects in medical imaging, film and television special effects, virtual reality, image restoration of cultural relics, banking business processing, etc. It is a research field of current computer vision and computer graphics. hotspot. Especially in the financial system, with the continuous expansion of the digital and networked business of the financi...
