Noise Removal in Image Using LPG-PCA (Local Pixel GroupingPrinciple Component Analysis) Algorithm
2014
IOSR Journal of Electronics and Communication Engineering
In this paper an effective algorithm for noise removal in an image is obtained by using PCA (principal component analysis) with LPG (Local Pixel Grouping). This technique ensures the preservation of image local structure. Here the pixels and its neighbors are treated as vector variables whose training samples are selected from local windows using block matching based LPG. This ensures only the similar samples are selected for the PCA transformation so that the desired local characteristics are
