Region of interest coding in jpeg 2000
WebThis paper details work undertaken on the application of an algorithm for visual attention (VA) to region of interest (ROI) coding in JPEG 2000 (JP2K). In this way, an "interest ordered" progressive bit-stream is produced where the regions highlighted by the VA algorithm are presented first in bit-stream. The paper briefly outlines the terminology used … WebRegions of Interest (ROI) image coding enables the regions important to medical diagnosis to be encoded and transmitted at higher quality than the other regions. ...

The paper briefly outlines the JPEG … WebThe experimental results show that there are a number of parameters that control the effectiveness of ROI coding, the most important being the size and number of regions of …
Weblossless coding, progressive transmission by pixel accuracy and by resolution, robustness to the presence of bit-errors and region-of-interest coding, are some representative features. It is interesting to note that JPEG2000 is being designed to address the requirements of a diversity of applications, e.g. Internet, WebThis project aims to primarily implement decoding of the JPEG 2000 ISO 15444 Part 1 Core coding system.
