Embodiment Construction

[0052] Image enhancement is a method to improve the visual effect of an image. Generally speaking, image enhancement refers to adjusting the brightness, saturation, and contrast of an image. At present, a large number of pictures circulated on the Internet have poor visual effects, and it is often difficult for Internet users to find pictures with good image content and image color. On the other hand, mobile phone photography has also become a way for most people to record their lives, but the photos taken by mobile phones are often difficult to meet the visual needs of users.

[0053]The inventor found in the process of implementing the technical solution of the present application that most of the current image enhancement algorithms use fixed parameter values ​​to adjust the pixel values ​​of each channel in the image, and even use fixed parameters to adjust the three channels (RGB channel ) pixel value. However, this method has a single effect and is prone to problems suc...

Abstract

Embodiments of the present application provide an image processing method and device. The method includes: obtaining a training sample set, the training sample set including a plurality of original image samples and corresponding enhanced image samples; training a pre-constructed CNN image processing network based on the training sample set to obtain a corresponding image enhancement model; Perform image enhancement on the input image based on the image enhancement model to obtain a preliminary enhanced image; obtain the fitting function corresponding to the preliminary enhanced image, and input the preliminary enhanced image into the fitting function for fitting calculation. , to obtain the final enhanced image. Therefore, this application combines deep learning and fitting functions to enhance the image, which can give the image appropriate enhancement effects according to different scenarios, thereby achieving the user's expected visual effects, greatly improving the traditional solution where the image enhancement effect is single and colors are prone to appear. Problems such as unnaturalness, color blocks, color casts, and unnatural transitions.
