[A medical ultrasonic image compression method based on vector quantization].

Abstract

In this paper we presented a new compression intension based on VQ with an in tension to provide an efficient approach to compressing medical ultrasonic images and thus make the establishment of a medical multimedia database possible. The major advantages of this coding scheme are: high compression rate, low distortion, higher speed of encoding procedure as compared with ordinary VQ. These benefits are mainly due to the unique design of the codebook and enhanced table look-up techniques. In addition, a comparison of this scheme with JPEG compression method (at high compression rate) was presented.
