Detection method of underwater weak target detection system based on logical stochastic resonance

Abstract

The invention provides a detection method of an underwater weak target detection system based on logical stochastic resonance, which includes an image acquisition unit, a frame difference method unit, a weak target region extraction unit, a logical stochastic resonance unit, a thresholder and a genetic network unit, and selects Three consecutive frames of images are input to the frame difference method unit to obtain the area where the weak target is located, and at the same time, the selected intermediate frame image is input to the weak target area extraction unit, and the area where the weak target is located is input to the weak target area extraction unit to obtain the image of the target area , which is expanded one-dimensionally along the direction perpendicular to the incident light and then input to the logic stochastic resonance unit, the output signal of the logic stochastic resonance unit is input to the thresholder to distinguish the background pixels and weak target pixels in the image of the target area to detect weak For the target image, the present invention effectively reduces the calculation amount, and at the same time, can effectively detect the weak target existing in the video image, and greatly improves the detection distance of the underwater target.

Description

technical field [0001] The invention relates to the technical field of underwater computer vision, in particular to a detection method of an underwater weak target detection system based on logic stochastic resonance. Background technique [0002] The earth is a blue water sphere, and the ocean area accounts for 70.8%. It has a vast underwater space and underwater resources. The exploration and utilization of ocean resources will greatly benefit the progress of human society. People have been working hard to find various Approaches to understanding and exploiting the underwater environment. However, due to the large amount of light absorption and scattering by the water body, especially when the underwater target is weak, the background noise is more abundant, making the target in the video taken by the underwater camera extremely blurred, which restricts the detection of underwater targets. technology development. Traditional underwater imaging processing is unsatisfactor...
