Abstract

The invention belongs to the technical field of underwater image processing, discloses an underwater image color enhancement method based on latent low-rank representation and image fusion, and specifically relates to a method capable of performing color correction, defogging, and detail enhancement on underwater images The method comprises the following steps: 1) using a color balance method with color compensation to eliminate the color cast in the imaging result caused by the attenuation characteristics of lighting or light of different colors in water, so as to restore the natural color of the image; 2) using The characteristics of the similarity between fog imaging and underwater light propagation are to perform defogging operations on the image to make the image more in line with the perception habits of the human eye; 3) Use latent low-rank representation to decompose the image to preserve the details in the image to the greatest extent , enhance the edge and details of the scene; 4) obtain the enhanced image through the method of image fusion. The invention can significantly improve the quality of underwater images and lay a foundation for researches on image feature extraction, target recognition, tracking and the like.

Description

technical field [0001] The invention belongs to the technical field of underwater image processing, and in particular relates to an underwater image color enhancement method based on latent low-rank representation and image fusion. Background technique [0002] In recent years, with the scarcity of terrestrial resources, people have begun to pay attention to marine resources, and underwater image processing has gradually become the focus of research in related fields. Underwater images are an important carrier of ocean information, but the complex underwater environment and harsh lighting conditions make the acquired underwater images seriously degraded. Due to the scattering and absorption of water, the underwater images have low contrast and high noise. , texture blur, serious fogging effect, blue-green tone and color distortion, etc., have a serious impact on the feature processing and target recognition and tracking of subsequent underwater images. Therefore, in order t...
