| titleOfInvention | A denoising processing system and method of a three-dimensional filter denoising algorithm |
| abstract | The invention discloses a denoising processing system and method of a three-dimensional filter denoising algorithm, comprising an image cache unit, a block matching unit, a three-dimensional filter unit and an aggregation unit, an image cache unit, a block matching unit, a three-dimensional filter unit and an aggregation unit in sequence Connect; the method is: divide the original image part into N 4x4 reference blocks; each reference block performs full search block matching in its respective 7x7 search area; select 8 candidate blocks with the smallest SAD as matching blocks; pair 8 Perform 3D Hadamard transform on each matching block; perform hard thresholding according to noise estimation parameters; perform 3D Hadamard inverse transform on the obtained 8 matrices; then map back to its original position in the image, and Estimates are averaged. The present invention performs filtering and denoising according to noise estimation parameters, has good denoising effect, and at the same time has low system resource occupation rate, and can achieve high-speed real-time denoising processing. |
