In free-viewpoint video, there is a recent trend to represent scene objects as solids rather
than using multiple depth maps. Point clouds have been used in computer graphics for a …

We have provided an overview of state-of-the-art ROI coding techniques applied to medical
images. These techniques are classified according to the image type they apply to; thus the …

In this world of big data, the development and exploitation of medical technology is vastly
increasing and especially in big biomedical imaging modalities available across medicine …

In order to ef ciently archive and transmit large 3D models, lossy and lossless compression
methods are needed. We propose a compression scheme for coordinate data of point-based …

We propose disparity-compensated lifting for wavelet compression of light fields. With this
approach, we obtain the benefits of wavelet coding, such as scalability in all dimensions, as …

Spatial resolution and contrast sensitivity requirements for some types of medical image
techniques, including mammography, delay the implementation of new digital technologies …

In many image-coding applications such as Web browsing, image databases, and
telemedicine, it is useful to reconstruct only a region of interest (ROI) before the rest of the …

Most of the commercial medical image viewers do not provide scalability in image
compression and/or region of interest (ROI) encoding/decoding. Furthermore, these viewers …

This paper addresses the problem of efficient predictive lossless compression on the
regions of interest (ROIs) in the hyperspectral images with no-data regions. We propose a …

An optimal three-dimensional (3-D) coefficient tree structure for 3-D zerotree wavelet video
coding is considered in this paper. The 3-D zerotree wavelet video coding is inspired by the …
