Problems solved by technology

[0003] The existing image interpolation methods are limited to the existing simple function forms, such as linear interpolation, bilinear interpolation, etc. These interpolation processes have nothing to do with the spatial position and content information of pixels, and cannot achieve effective fitting
Therefore, the image quality obtained by using the interpolation processing of the prior art is poor and the degree of restoration is low

Embodiment Construction

[0028] In the present disclosure, unless otherwise stated, using the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, temporal relationship or importance relationship of these elements, and such terms are only used for Distinguishes one element from another. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, they may also refer to different instances based on contextual description.

[0029] The terminology used in describing various examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, there may be one or more elements. In addition, the term "and / or" used in the present disclosure covers any one and all possible combinations of the listed items.

Abstract

The invention relates to an image interpolation method and device, and relates to the technical field of computer vision. The method comprises the following steps: determining an effective feature gradient map and a diffusion coefficient matrix of a to-be-processed image; determining effective transmission information of the to-be-processed image based on the effective feature gradient map and the diffusion coefficient matrix; and updating the to-be-processed image based on the effective transmission information to obtain an interpolation image.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, in particular to an image interpolation method and its device, equipment and medium. Background technique [0002] Interpolation refers to using known data to predict unknown data, while image interpolation refers to given a pixel and predicting the value of the pixel based on the information of its surrounding pixels. Since image interpolation technology can predict pixel information, it can be used for refinement of a given image. [0003] Existing image interpolation methods are limited to existing simple function forms, such as linear interpolation, bilinear interpolation, etc. These interpolation processes have nothing to do with the spatial position and content information of pixels, and cannot achieve effective fitting. Therefore, the image quality obtained by using the interpolation processing of the prior art is poor and the restoration degree is low. Therefore, how to...
