We combine a mask motion detection algorithm with both the WAAVES adaptive compression algorithm (resulting into MMWaaves) and a JPEG2000 coder (resulting into MMJPEG2000) for the compression of medical images sequences. Several images were compressed using Waaves, MMWaaves, and MMJPEG2000 to observe which tool provided the best visual quality while(More)
In this paper, we propose a new approach to compress Electroencephalogram (EEG) signals using the WAAVES compression algorithm and Independent Component Analyses (ICA). Firstly, ICA is applied to the 1D-EEG signals as a preprocessing stage to uncorrelate signals. Then, the output of the ICA is scaled and reformatted into a 2D-matrix to be compressed as an(More)
Diagnostic quality is an essential requirement in the medical images compression field to avoid misdiagnosis by radiologists. In this paper, a novel study on using the logarithm in medical images compression is presented. Two novel compression schemes are proposed to improve the image quality. The proposed compression schemes relies on discrete wavelet(More)
