Abstract

The invention relates to an underwater image enhancement method based on an optimal restoration parameter. The method comprises steps that S1, images are inputted, hundreds of high quality underwaterpictures are collected as samples, and new underwater image dark channel apriority is acquired; S2, RGB three-channel transmission map estimation based on new UDCP conclusion is carried out; S3, backlight estimation based on a fusion method is carried out; and S4, image restoration is carried out. The method is advantaged in that the final output shows better enhancement in contrast, saturation and brightness, the method is suitable for the underwater images in different environments, and the enhanced images are applicable to underwater exploration, marine resource assessment and target identification applications.

Description

technical field

[0001] The invention relates to the technical field of underwater image restoration and enhancement, in particular to an underwater image enhancement method based on optimal restoration parameters. Background technique

[0002] The sea world contains a large amount of resources. Under the problems of land population explosion, resource depletion, and environmental degradation, developing and protecting the ocean is an important and strategic choice. The theory and practice of the transmission, acquisition and processing of marine information have played a key role in the rational development and protection of marine ecology, marine resources, and marine diversity.

[0003] Underwater images are an important carrier of marine information. However, compared with images in natural environments, underwater images have more complex imaging principles, low contrast, and poor visibility. These factors have hindered the research on marine ecology, marine resources, ...
