DICOM image compression by wavelet transform

摘要

Efficient image compression solutions are becoming more critical with the recent intensive growth of data and multimedia-based web applications. In this paper we propose an efficient DICOM image compression based on wavelet transform. The basic concepts of graphical image storage and currently used compression algorithms, are discussed Several types of wavelets, including Haar, Daubechies, and biorthogonal spline are tested An adaptative quantization method has been introduced, it has been followed by an arithmetic coding. Besides, images in the standard medical format DICOM are considered in our application.
