In this paper, we are proposing a wavelet-based progressive transmission algorithm for medical images. The system should fulfill certain criteria of medical image transmission. To accomplish the target, we have studied several potential integer wavelet transforms and waveletbased image coders that best work for the system. The system is also enhanced with region-of-interest (ROI) coding, which ...

Large terrain databases require a great number of polygons and textures. In consequence, transmission of terrain data over slow networks is still worrying. Multiresolution models allow progressive transmission, that is, the transmission of a simple model followed by successive refinements. In this work we describe a new multiresolution model called Geometric-Textured Bitree (GTB) that enables p...

The recent developments in the multimedia communication technology made it necessary to provide image compression standards with a number of functionalities such as the capability of progressive transmission of the code and more conformity with the human visual perception. The general purpose still image compression standard JPEG2000 for example, incorporates many such functionalities. This the...

a hepatitis b virus (hbv) infection is a global public health problem. in endemic areas, hbv infection occurs mainly during infancy and early childhood, with mother to child transmission (mtct) accounting for approximately half of the transmission routes of chronic hbv infections. prevention of mtct is an essential step in reducing the global burden of chronic hbv. natal transmission accounts f...

The progressive transmission of map data over World Wide Web provides the users with a self-adaptive strategy to access remote data. It not only speeds up the web transfer but also offers an efficient navigation guide in information acquisition. The key technology in this transmission is the efficient multiple representation of spatial data and pre-organization on server site. This paper aims a...

We investigate the problem of selecting blocklength and code rate for progressive image transmission, motivated by turbo coding methods where performance improves with blocklength. The problem is to balance the tradeoff among error protection, source coding rate, and delay. We propose a general performance measure for evaluating progressive transmission and use dynamic programming to determine ...
