Abstract

The invention is suitable for the field of image processing, and provides a DCE-based low-illumination image enhancement method and system and related equipment, and the method comprises the steps: obtaining video data of a real scene; performing frame splitting processing on the video data to obtain frame splitting pictures, screening out a test data set containing paired picture data from the frame splitting pictures, and screening out a training data set containing pictures with different exposure degrees from an SICE data set; performing iterative training on a preset enhancement model by using the training data set, and storing the preset enhancement model after the iterative training as a low-illumination enhancement model; and performing low-illumination enhancement on the test data set by using the low-illumination enhancement model. According to the method, the loss of the original information of the image in the image enhancement process is prevented, the edge information in the image is further protected, and the image enhancement effect is improved.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a low-illumination image enhancement method, system and related equipment based on DCE. Background technique [0002] In the low-light environment and under the conditions of unsatisfactory camera equipment, the collected images have problems such as low brightness, low contrast, and high noise, which not only affect the beauty of the image and human visual perception, but also reduce the use of normal lighting images. Performance on high-level vision tasks. [0003] With the continuous development of low-light image enhancement technology, researchers have proposed various methods to improve the subjective and objective quality of low-light images. At present, the common low-light image enhancement algorithms include the method based on histogram equalization, the low-light image enhancement algorithm based on Retinex theory, and the low-light image enhancement algor...
