Wavelet-based space-frequency compression of ultrasound images.

Wavelet-based space-frequency compression of ultrasound images.

This paper describes the compression of grayscale medical ultrasound images using a recent compression technique, i.e., space-frequency segmentation (SITS). This method finds the rate-distortion optimal representation of an image from a large set of possible space-frequency partitions and quantizer...
