Summary: | The invention provides an underwater image restoration method based on a secondary guided transmission image. The method comprises the following steps: firstly, inverting a red channel, and solving background light on an inverted image by using dark channel prior; secondly, solving saturation through an original image; solving a rough transmission image according to background light, saturation and red dark channel prior, decomposing the rough transmission image into a basic image and a detail image by using guided filtering, performing Laplace filtering processing on the basic image, performing guided filtering processing on the detail image, and reconstructing the processed image to obtain a refined transmission image; performing image restoration in combination with an underwater imaging model; and finally, performing automatic color gradation processing on the restored image to obtain a final restored image. The invention provides the underwater image restoration method based on the secondary guided trans |
