Embedded Zero-tree Wavelet (EZW) Image Compression Using Multi-Threshold
다중 임계값을 이용한 임베디드 제로트리 웨이블렛(EZW) 영상압축
Abstract
In this paper, the embedded zero-tree wavelet image compression method using multi- threshold is proposed, which can reduce the scanning and symbol redundancy of the existing embedded zero-tree wavelet (EZW) method and enable more efficient coding. In the proposed scheme, a multi-threshold is constructed with the maximum absolute values from each subband decomposed by the wavelet transforms of the input image data. The multi-threshold values are compared with the threshold value T
