Digital Imaging and Communication in Medicine (DICOM) standard promotes the communication of digital image in the medical imaging environment. A picture archiving and communication system(PACS) is an electronic and ideally film less information system for acquiring, transporting, storing and electronically displaying medical images.

This paper presents an efficient denoising technique for removal of noise from digital images by combining filtering in both the transform (wavelet) domain and the spatial domain. The noise under consideration is AWGN and is treated as a Gaussian random variable. In this work the Karhunen-Loeve transform (PCA) is applied in wavelet packet domain that(More)
