摘要:The proficient Image Compression of Medical Images U sing the Discrete Wavelet Transformation (DWT) and the fuzzy c-means clustering technique.The goal is to achieve higher compressio n rates b y applying different compression thresholds for the wavelet coefficients of each DWT band, in terms of how they are clustered according to their absolute values.Image compression methodologies utilizing the DWT apply it to the whole original image. That is, different comp ression ratios are applied to the wavelet coefficients belonging in the different regions o f interest, in which either each wavelet domain band of the transformed image or the image itself is clustered, respectively. Regarding the first method, its reconstruction process involves using the inverse DWT on the remaining wavelet coefficients. Concerning the second method, its reconstruction process involves linear co mbination of the reconstructed regions of interest. An experimental study is conducted to qualitatively assessing both approaches in comparison with the original DWT compression technique, when applied to a set of medical images.
