Problems solved by technology

[0006] The commonly used linear interpolation algorithms belong to the finite pulse low-pass filter with a limited window size. When the input image is enlarged with high resolution, it will obviously cause ringing, jagged, blur and other phenomena in the output image. Therefore, how to zoom in Maintaining less image distortion at more times the resolution has been a major research topic for many years

Embodiment Construction

[0049] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0050] like figure 1 Shown, a kind of system of image, video super-resolution enlargement, it comprises first memory, first buffer, interpolation filter, second buffer, decimation filter, the 3rd buffer, subtraction module, the 4th Buffer, Patch matching module, the fifth buffer, correction module, addition module, the sixth buffer, bicubic interpolation down-sampling module and the second memory;

[0051] The first memory receives the input original image, the output end is connected with the original image input end of the first buffer, the output end 1 of the first buffer is connected with the interpolation filter, and the output end of the interpolation filter is connected with the second The buffers are connected, the output terminal ...

Abstract

The invention discloses an image and video super-resolution magnification system and method. The system comprises a first memory, a first buffer, an interpolation filter, a second buffer, a decimation filter, a third buffer, a subtraction module, a fourth buffer, a Patch matching module, a fifth buffer, a correction module, an addition module, a sixth buffer, a bicubic interpolation under-sampling module and a second memory. By the adoption of the image and video super-resolution magnification system and method, acceptable subjective image quality can be acquired in the aspects of weakening ringing noise, image blurs, marginal sawteeth and the like, and the image and video super-resolution magnification system and method can be used for common camera and DV images with the large resolution and the like and also used for magnification display of internet pictures with the small resolution.

Description

technical field [0001] The invention relates to a system and method for image and video super-resolution amplification, which is applied to the fields of digital image processing, video processing, radio and television production, up-conversion, nonlinear editing and the like. Background technique [0002] With the development of digital image processing technology and display device technology, increasing the resolution of images for further processing has become a common image editing operation; no matter from theory or practice, how to reproduce images with less distortion The color value of the missing pixels in the middle after the resolution is increased is a very challenging task. [0003] The simplest and most efficient algorithm for improving image resolution is to directly copy the color values ​​of adjacent pixels as the color values ​​of the missing pixels in the middle. The main defect is that it will cause jagged edges of the output image. [0004] A further a...
