Problems solved by technology

This method can effectively smooth out the jaggies in the image and improve the visual effect of the image, but it still has two problems: first, the anchor point constraint technology used in this method cannot make all the jaggies in the image disappear. is sufficiently smoothed, and destroys detailed texture information in the image
Second, this method does not solve the blur effect of the image very well

Embodiment Construction

[0043] The present invention will be described in detail below with reference to the accompanying drawings.

[0044] Although the traditional interpolation method can achieve good results at the low-frequency components of the image, but at the edge of the high-frequency component, that is, the image, it will bring some artificial traces due to interpolation errors, such as aliasing effects, blur effects, etc. These artificial traces Greatly affects the visual effect of the image.

[0045] The recent method of improving the visual effect of an image can reduce the jagged effect in the image to a certain extent, but it still cannot fully smooth each edge and may damage the detailed texture information of the image. In addition, it cannot improve Blurring effects due to initial interpolation errors. In order to overcome the limitations of the above technologies, the present invention proposes an image interpolation reconstruction method based on edge-sensitive level set diffusi...

Abstract

The invention provides an image interpolation reconstruct method based on single image with low resolution ratio that is a horizontal collect diffusion technique through using edge information limitation after interpolation using double three interpolations method with present standard. The method can improve a sawtooth effect in the image with high resolution ratio obtained by present standard interpolation method, and ensure detail information in the image from being destroyed. A double-edge filter technique through using edge information limitation can reduce blurring effect in the image with high resolution ratio effectively, and visual effect of the image with high resolution ratio is improved greatly.

Description

technical field [0001] The invention relates to an image construction method, in particular to an image interpolation reconstruction method based on a single low-resolution image. Background technique [0002] In most digital image applications, it is desirable to obtain high-resolution images. Higher resolution can provide more and clearer details, which is very critical in many fields. For example, medical images with higher resolution can help doctors judge the disease more accurately; in the process of satellite remote sensing imaging, high-resolution images often become the key to distinguish objects. In addition, high-resolution images also play an important role in forensic identification, vehicle license plate recognition and other fields. [0003] Just because of the widespread use of high-resolution images, various methods have emerged in recent years to improve the quality of the resulting high-resolution images. In general, these methods can be divided into tw...
