Abstract

We present a wavelet-based video codec based on a 3-D (x,y,t) wavelet transformer, a uniform quantizer/dequantizer and an arithmetic encoder/decoder. The wavelet transformer uses biorthogonal (9,7) Antonini wavelets in the two spatial dimensions and Haar wavelets in the time dimension. Multiple levels of decomposition are supported. The codec has been applied to pre-scan-converted (r-theta or polar coordinate) ultrasound image data and does not produce the type of blocking artifacts that occur in MPEG-compressed video. The PSNR (peak signal to noise ratio) at a given compression rate increases with the number of levels of decomposition: for our data at 50:1 compression, the PSNR increases from 18.4 dB at one level to 24.0 dB at four levels of decomposition. Our 3-D wavelet-based video codec provides the high compression rates required to transmit diagnostic ultrasound video over existing low bandwidth links without introducing the blocking artifacts which have been demonstrated to diminish clinical utility.
