Region of Interest Coding for JPEG2000 - IEEE Xplore

WebHuman visual attention mechanisms would direct the viewer's eye movements around the image to provide a sequence of fixations, which can be analysed, clustered and classified into regions of interest (ROI). These ROIs can be used by the JPEG 2000 image coding standard to encode and prioritise image content and improve recognition performance. 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,

WebDec 14, 2000 · ISO/IEC TR 29170-1:2024 recommends best practices for coding system evaluation of images and image sequences. ISO/IEC TR 29170-1:2024 defines a common vocabulary of terms for coding system evaluation and divides evaluation methods into three broad categories: a) subjective assessment; b) objective assessment; c) computational … WebOne significant feature of JPEG 2000 is the possibility of defining regions of interest in an image 5. These regions of interest are coded with better quality than the rest of the image. This is done by scaling up, or DC shifting, the coefficients so that the bits associated with the regions of interest are placed in higher bit-planes.
