Apparatus and Method of Wavelet Transform based on Update-Prediction Lifting, Adaptive Prediction Apparatus and Method therefore, and Recording Medium therefor

摘要

The present invention relates to an update-predictive structure lifting-based wavelet transform apparatus and method, an adaptive predicting apparatus and method therefor, and a recording medium therefor. More particularly, the present invention relates to an update- Sets a plurality of prediction direction candidate groups around the set first update even-numbered polyhedral samples, selects a first prediction direction for minimizing energy in the high band among the plurality of prediction direction candidate groups, Estimating a first predicted value based on an updated even-numbered polyphase sample corresponding to the first predicted direction and a first predicted direction thereof, calculating a residual odd polyphase sample by subtracting the first predicted value from the corresponding odd- By using directional wavelet transform based on lifting method, When removing the correlations, it provides a great effect in the high-band signal energy seonggim to increase the encoding efficiency.;Image, compression, update, prediction, wavelet, odd polyphase sample, even polyphase sample
