Embodiment Construction

[0051] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] The present invention can use a computer to train and infer the network, and realize it using the Tensorflow deep learning framework under the windows operating system. The specific experimental environment configuration is as follows:

[0053] GPU NVIDIA GeForce RTX 2060SUPER CPU AMD Ryzen 5 3600 6-Core Processor Programming language Python 3.7 Deep Learning Framework TensorFlow-GPU 2.1.0

[0054] The present invention mainly includes two parts: (1) using the SFU Grayball data set used for color constant calculation as a training set, and adopting the method of artificially adding simulated complex light sources, expanding this data set to be suitable for training uniform light sources, The data set required for the experiments of the color constancy model of non-uniform light sources.

Abstract

The invention provides a color cast removal model based on a generative adversarial network, which is used for solving the problem that a traditional color constancy algorithm cannot process the image color cast under a complex light source. The model is expanded on the basis of a core viewpoint of an end-to-end model of a conditional generative adversarial nets (CGAN), the U-Net connection is adopted as a generator network structure, a Markov discriminator serves as a discriminator network structure, a loss function capable of better reflecting the tone information is introduced to optimize a training model, and finally an image with color cast removed is obtained. According to the method, images with inconsistent input color projection can be received, compared with the existing method, two tasks of color cast removal and image resolution improvement under any light source can be completed at the same time, and a better enhancement effect can be achieved.

Description

technical field [0001] The invention belongs to computer vision enhancement technology, in particular to an image enhancement method based on a generative confrontation network for color shift removal. Background technique [0002] In the field of computer vision research, image understanding is one of its important research directions, and the basis of image understanding is image features, in which color is one of the most important underlying features of images, and has great potential in image feature extraction and feature learning. strong reference. However, the color information of objects in image scenes is unstable, and the color of objects is easily affected by changes in light sources. The purpose of removing the color cast of the image is to perceive the color correctly and obtain the real color information of the object that has nothing to do with the change of the light source. [0003] Since the color constancy of the color image itself is limited and compli...
