Line 14: == Introduction == '''Embedded zerotree wavelet algorithm''' (EZW) isas developed by J. Shapiro in 1993~~. This method~~, enables scalable image transmission and decoding. ~~And it~~It is based on four key concepts~~. At~~: first, it should be a discrete wavelet transform or hierarchical subband decomposition.; ~~Second~~second, it should predict the absence of significant information when exploring the self-similarity inherent in images.; ~~Third~~third, it has entropy-coded successive-approximation quantization., and ~~Last~~fourth, it is enable to achieve universal lossless data compression via adaptive arithmetic coding. Besides, the EZW algorithm also contains the following features:
