TLDR
Experimental results show that the proposed scheme can increase 25~30% compression ratio of original JPEG medical data compression system with similar visual quality.Abstract:
In this paper, a new medical image compression algorithm using cubic spline interpolation (CSI) is presented for
telemedicine applications. The CSI is developed in order to subsample image data with minimal distortion and to
achieve image compression. It has been shown in literatures that the CSI can be combined with the JPEG or JPEG2000
algorithm to develop a modified JPEG or JPEG2000 codec, which obtains a higher compression ratio and a better
quality of reconstructed image than the standard JPEG and JPEG2000 codecs. This paper further makes use of the
modified JPEG codec to medical image compression. Experimental results show that the proposed scheme can increase
25~30% compression ratio of original JPEG medical data compression system with similar visual quality. This system
can reduce the loading of telecommunication networks and is quite suitable for low bit-rate telemedicine applications.read more
