Abstract

The invention provides an underwater fish image enhancement method and system, computer equipment and a storage medium. The method comprises the following steps: acquiring a to-be-enhanced underwater fish image of seawater cage culture; performing CIE-Lab space adaptive stretching on the underwater fish image to be enhanced to obtain a first enhanced image; performing color equalization processing on the first enhanced image according to attenuation characteristics of different light waves propagating in water to obtain a second enhanced image; and performing contrast stretching on the second enhanced image to obtain an enhanced underwater fish image. According to the method, CIE-Lab space adaptive stretching, color equalization processing and contrast stretching processing are sequentially carried out on the actually acquired underwater fish image, the underwater fish image can be improved from three angles of brightness, color equalization and contrast, and the underwater fish image with a better visual effect is obtained; therefore, a good technical support is provided for image analysis and processing in intelligent fishery breeding.

Description

Technical field [0001] The present invention relates to the field of computer vision and underwater image enhancement, and more particularly to a low underwater fish image enhancement method, system, computer device, and storage medium. Background technique [0002] With the continuous development of science and technology, fisheries have gradually developed from traditional farming methods to wisdom, and people began to introduce emerging technologies such as Internet of Things, large data and image processing in fisheries farming. In the way in which fish photos underwater are intelligently analyzed, the breeding data such as breeding environment, fish group density, and fish group volume is monitored in order to make a penetration of fish groups and health. Breeding management or assistance management, etc., enabling aquaculture into modern, scientific and intelligent, further providing reliable security for fishery stability. However, the quality of underwater fish images has...
