Abstract

The invention is applied in the technical field of video processing, and provides a super-resolution processing method suitable for video. The method comprises the following steps of: receiving a low-resolution image; dividing the low-resolution image into a plurality of blocks; searching high-resolution patches in a pre-trained database; sticking the high-resolution patches back to the pluralityof blocks of the low-resolution image by an image splicing method or an oblique angle type method and calculating the compatibility by a two-dimensional hidden Markov model; and generating a super-resolution image. The patches are stuck back in the image splicing or oblique angle mode by using the two-dimensional hidden Markov model in the embodiment of the invention, so that the integral execution efficiency can be promoted; and the peak signal to noise ratio (PSNR) of the acquired super-resolution image can promote the quality of the image.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to an image processing method, more specifically, a two-dimensional hidden Markov model-based super-resolution processing method suitable for video. Background technique [0002] With the development and promotion of various display technologies, various high-resolution display devices (displays, televisions or others) are widely used in general households or professional fields. From the early standard resolution (Standard Definition, SD) to the more common high resolution (High Definition, HD) or full high resolution (Full HD) standard, the resolution capability provided by the Full HD display can reach "1920× 1080", and the resolution of some professional monitors has exceeded this standard, which can be widely used in entertainment, medical or other fields. [0003] In order to make full use of the high-resolution capability of the display, users also hope ...
