摘要

The present invention relates to a three-dimensional block division scheme for the wavelet transform based video coding, and more specifically relates to a three-dimensional block division method for the continuous input space to a two-dimensional wavelet transformation to the video frame and a temporal wavelet transform applying a one-dimensional wavelet transform based video coding. ; wavelet transform of the present invention a three-dimensional block division scheme is to apply a two-dimensional wavelet transform and one-dimensional wavelet transformation to the time-space image in the input video frames based on a continuous phase for video encoding; No motion prediction and the motion compensation process, the step of coding the n-th MSB of the absolute values of the wavelet coefficients; N is the beginning of a wavelet is selected to the power of 2 of the maximum value the absolute value of the transform coefficients, the value of n for each phase is decreased by one step; A two-dimensional space of the wavelet coefficients and the one-dimensional time-step to collect the initial three-dimensional blocks in accordance with the sub-band; The technical features and the n-th MSB is made of a step of repeatedly performing the divided block to have a value of zero for the absolute value of all the coefficients in the three-dimensional blocks. ; Thus, the The three-dimensional block division scheme for the wavelet transform based video coding of the invention, the pay higher royalty from overseas may be substituted for wavelet-based video encoder using. In addition, there is a high compression effect than traditional wavelet-based video compression technology.
