Problems solved by technology

However, although the improved resolution improvement method optimizes the edge part of the image, the algorithm logic is more complicated and does not optimize the rest of the image; while the resolution improvement method based on deep learning can improve the overall quality of the image, but consumes computing resources Huge, costly to implement
[0007] In summary, there are still many problems in the existing resolution enhancement methods, which need to be improved by technicians

Embodiment Construction

[0045] As mentioned in the background art, resolution enhancement methods are more commonly used in electronic products such as mobile phones, computers, and televisions. In practical applications, traditional resolution enhancement methods may include: a nearest neighbor interpolation (Nearest interpolation) algorithm, a bilinear interpolation (Bilinear interpolation) algorithm, a bicubic interpolation (Bicubic interpolation) algorithm, and the like. However, blurring and aliasing are likely to occur in images obtained through the above-mentioned traditional resolution enhancement method.

[0046] After the research of technicians, some improved resolution improvement methods have been proposed, such as direction-based interpolation (Directional interpolation) algorithm, example-based super-resolution (Example based superresolution) algorithm, sparse representation-based super-resolution (Sparse representation superresolution) ) algorithm, etc. Compared with the traditional ...

Abstract

The invention discloses an image and video processing method and system, a data processing device and a medium, and the image processing method comprises the steps: extracting the image features of an original image, and obtaining a first detail image; selecting a target pixel and a local area from the first detail image, wherein the local area comprises the target pixel; based on a statistical relationship between other pixels in the local area and the target pixel, calculating to obtain corresponding statistical feature information, and updating the statistical feature information into color information of the target pixel in the first detail image to obtain a second detail image; and combining the second detail image and the original image to obtain a composite image. According to the scheme, the image quality and the processing efficiency can be improved.

Description

technical field [0001] The embodiments of this specification relate to the technical field of data processing, and in particular to an image and video processing method and system thereof, data processing equipment, and media. Background technique [0002] With the development of consumer electronics, people can shoot and publish multimedia information such as videos and images anytime and anywhere, and can obtain a variety of multimedia information through communication channels. It can be said that modern people are living in the era of information explosion. [0003] In order to improve the viewing experience of users, the demand for displaying multimedia information on different devices has also increased, which has prompted the rapid development of display technology, from CRT (Cathode Ray Tube, cathode ray tube) technology to LCD (Liquid Crystal Display, liquid crystal display) technology From OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode, or Organic...
