Embodiment Construction
[0047] The present invention provides an iterative depth map structure restoration method based on RGB-D SSIM structure similarity. First, the edge of the input depth map is detected, and the edge is expanded, and the expanded area is marked as a potential structural distortion area, and then the Each pixel in the potential structural distortion area judges whether it is distorted, and generates a structural distortion metric index. The distorted pixel uses the product of the Gaussian weight of the color image and the structural distortion metric index to construct a restoration weight, and performs guided restoration through a weighted median filter, and then Guided filtering is performed in the distorted area, and the completed result map continues to iterate according to the above steps until the set termination iteration condition is met, and the calculation ends with the output depth map, otherwise it will continue to iterate until the maximum number of iterations is reache...
