Abstract:

In order to ease the stair casing artifacts and better preserve the details of the image after denoising, this paper proposes an image denoising algorithm based on the boosting high order non-convex total variation (HONTV) model. By averaging each denoised image and the original image as the input of the next cycle of the boosting HONTV model and updating the parameters, the augmented Lagrangian method and the alternating direction method of multipliers are used to solve the model. After multiple iterations, the resulting denoised image contains more detail information. In the image denoising method based on total variation, the experimental results show that the proposed algorithm outperforms the comparison algorithm in terms of visual performance and objective evaluation index for adding Gaussian white noise test images and videos with different standard deviations.

Key words: high order non-convex total variation (HONTV), image denoising, augmented Lagrangian method, alternating direction method of multipliers
