This paper presents a study on directions of principal structures of the images and their effects when the UTV decomposition is employed. The relationship between the UTV decomposition and SVD is also explored. The proposed image denoising algorithm illustrates that the UTV decomposition can efficiently decompose images with vertical/horizontal structures into only a few component as well as the SVD. © 2008 IEEE.Mahidol UniversityComputer ScienceConference PaperSCOPUS10.1109/ICALIP.2008.4590114
