A Rotational Invariant Non-local Mean

초록

The image restoration and noise reduction are used to improve image quality and to develop more robust and high performance algorithms to solve denoising problems in the image processing. Every approach has their own limitations and more practicable properties with the specific conditions. This paper considers rotational transformation with non-local means denoising algorithm. The non-local means denoising algorithm use repetitive patterns in the image for noise reduction. Therefore, the affine transformations will extend search space of the problem and will cause of more qualitative results.
