Collective rationality for the allocation of bits (CORAL) is a software-based implementation of a new coder scheme that in absence of a priori knowledge about regions of interest propose a new method for bit allocation which can be used with reasonable internal consistency and acceptable image fidelity. The effectiveness of a coding method can be improved through a space-varying filterbank tree representation of the image, and this property can be conveniently exploited using appropriate bit allocation strategies among the spatial segments of the image.

A visual distinctness metric for coder performance evaluation: CG is a visual distinctness metric that constitutes an alternative to PSNR for evaluating the performance of compression methods. (Computer Vision Group / University of Granada. Spain)

Camera Array Viewer (CAView) is a free package about a 3D viewer from multiple input images (image-based rendering) using on-the-fly geometry reconstruction. CAView includes an algorithm that reconstructs the scene geometry in the form of a 2D mesh model, which runs fast and gives good rendering quality. It could be easily extended and used in 3D video conferencing applications. (by Cha Zhang / Advanced Multimedia Processing Lab / Carnegie Mellon University)
