Embodiment Construction
[0106] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Embodiments of the present invention and its implementation process are as follows:
[0107]The underwater image processed by the embodiment of the present invention is as follows figure 2 As shown, including a test image and an image to be registered. The two underwater images are taken from two angles of the same large scene, and the two images have common parts, so it is necessary to register and stitch the two underwater images to output one image. Specific steps can refer to figure 1 The flowchart in .
[0108] Step 1. Underwater image preprocessing: image enhancement
[0109] The underwater image is enhanced by using improved white balance algorithm and CLAHE algorithm based on linear interpolation.
[0110] 1.1) Use the improved white balance algorithm to perform white balance processing on underwater images.
[0111] 1.1....
