Embodiment Construction
[0052] An underwater color video image enhancement method. Firstly, a degradation model is constructed based on the propagation characteristics of visible light in water and the light composition on the image surface, and the image is restored by applying the dark channel prior law to remove the fuzzy noise caused by scattering. For the inhomogeneity of visible light absorption, apply the Retinex theory (Retinex is a combination of two phrases Retina of the retina and Cortex of the cerebral cortex) to enhance the image to sharpen and enrich the details, thereby improving the imaging blur of underwater color video images, Problems such as loss of detail and color cast have good robustness. The present invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings:
[0053] Such as figure 1 As shown, the reflected light irradiated by the underwater lighting source 2 on the underwater object 3 is projected onto the image sens...
