When the laser beam encounters different media or interfaces, scattering phenomena occur, making the laser energy distribution uneven, resulting in blurred edges and loss of details in the dual wave scattering laser image. Therefore, an improved multi-scale Retinex based dual wave scattering laser image enhancement method is proposed. Perform downsampling on dual wave scattering laser images to obtain estimated blur kernel parameters. Update the light point parameters based on the fuzzy kernel, estimate the original clear image, and achieve deblurring processing of dual wave scattering laser images. Expand global enhancement on the dual wave scattering laser image to enhance the global contrast of the dual wave scattering laser image. Replace the Gaussian filter in the multi-scale Retinex algorithm with a guided filter to improve the multi-scale Retinex algorithm. Using an improved multi-scale Retinex algorithm to filter and enhance dual wave scattering laser images. Finally, the DWT image fusion algorithm is used to fuse the global contrast enhancement results with the filtering enhancement results, completing the enhancement of dual wave scattering laser images. The experimental results demonstrate that the proposed method has a good dual wave scattering laser image enhancement effect and can effectively improve the visual quality of the image.
