Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] In related technologies, the terminal can not only enhance the low-light image by adjusting the RGB value, but also can enhance the low-light image captured in the low-light scene by using an algorithm based on the retinal cortex theory (Retinex theory). Specifically, the terminal can decompose the captured low-light image into a reflection layer (also called a reflection image) and an illumination map (also called an illumination image) based on an image decomposition method, and then directly use the reflection layer as the restoration result of the scene content , to obtain a restored image, or the light map can be used to fine-tune the reflective layer, and use the fine-tuned reflective layer as the restoration result of the ...

Abstract

The invention, which belongs to the field of image processing, discloses an image enhancement processing method and device. The method comprises: a specified image is processed by using a first regression network model to obtain a content feature map of the specified image; a gradient map of the specified image is processed by using a second regression network model to obtain an edge feature map of the specified image; and with a fusion processing model, the content feature map and the edge feature map are fused to obtain a restored image. With the image enhancement processing method, the processing effect is improved; and the processing efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image enhancement processing method and device. Background technique [0002] Image enhancement is a method for enhancing the useful information in the image and improving the visual effect of the image. [0003] In related technologies, for a low-light image captured in a low-light scene, the terminal generally uses a pre-configured image enhancement processing algorithm to perform enhancement processing on the low-light image. For example, the terminal may adjust the red, green and blue (RGB) values ​​of each pixel in the low-light image, thereby improving the visual effect of the low-light image. [0004] However, the image enhancement processing method in the related art can only increase the brightness of the entire low-light image as a whole, and its processing effect is relatively poor. Contents of the invention [0005] Embodiments of the present invention provide a...
