Medical Imaging 2000: Image Display and Visualization
Preserved Fulltext
In this work, we examine the feasibility of using MPEG-4 for coding ultrasound sequences. ...
The basis of these new capabilities is object-based video coding, in which a video image is represented as a set of regions of interest, or video objects, that are coded independently. ...
MPEG-4 is a new standard that extends previous MPEG standards to include support for user interaction and flexible display of multiple video bitstreams. 1,2 The basis of these new capabilities is object-based ...

In this paper, we present methods for both lossy and lossless compression of medical image sequences that only require compatibility with the Pixel Shader 2.0 standard, which is present even on relatively ...
However, a scenario where image sequences are kept in a compressed format in the internal memory and decompressed onthe-fly when displayed is difficult to implement due to performance issues. ...
