Image Thermal Radiation Restoration Method Based on Gaussian Double Ring Filter
Tianxu Zhang, Tian Wang · 2023
Traditional image restoration methods only study the restoration method based on the image itself, without considering the imaging physical process and the radiation characteristics of the object. Therefore, traditional methods have poor effects on image thermal radiation removal. Therefore, this paper proposes a joint frequency space time domain denoising and restoration algorithm that combines an improved Gaussian ring filter with smooth filtering, allowing the filter to freely adjust the radius, shape, size, and position of the ring according to different image conditions, in order to achieve better restoration effects. After processing the image using the algorithm proposed in this article, the signal-to-noise ratio is significantly improved, and the restored image retains more edge and detail information, effectively improving the resolution of the target image.
