摘要：
This paper introduces a, hovel method for noise reduction in medical images based oil concepts of the Non-Local Means algorithm. The main objective has beers to develop a method that; optimizes the processing speed to achieve practical applicability without compromising the quality of the resulting images. 11 database consisting of prototypes, composed of pixel neighborhoods originating from several images of similar motif, has been created. By using a dedicated data structure; here; Locality Sensitive Hashing (LSH), fast access to appropriate prototypes is granted. Experimental results show that the proposed method call be used to provide noise reduction wit's high quality results in a, fraction of the time required by the Non-local Means algorithm.
