| Abstract(in English) | In this paper, we propose two Non Local Means (NL-means) algorithms with robustness for Gaussian and mixed noise removal from images. The Non Local Means is well known as the powerful noise removal method without image blurring during filtering. Nevertheless, a similarity measure which determines the weights of NL-means tends to have errors because of the effect of Gaussian noise component. Therefore, we propose a new similarity measure for robustness against Gaussian noise. The similarity measure subtracts the noisy component from the sum of absolute difference between blocks. Moreover, we propose a robust NL-means method for Gaussian noise and impulsive noise (i.e., mixed noise ). The robust NL-means detects impulsive noise inside the block and eliminate the noisy pixels from the pixels used for the similarity measure. Through some simulations, the proposed methods are shown to give effective results than the conventional NL-means. |
