In the paper a new metric for comparing image quality assessment databases is presented. Its purpose is to show the real coverage of the database in Spatial information vs. Colorfulness space. Currently used metrics are vulnerable to databases having large uncovered areas within convex hull. Proposed method takes into account existing metrics but provides additional fill rate parameter, which define...
The perception of the spatial effect of 3D video is influenced by various factors. One of the most interesting and important factors is the content of the observed video sequence. This factor is relatively little investigated. The content of the scene can be described by particular parameters. The parameters have to describe spatial, temporal, depth and brightness distribution in sequences. We have...
Segmentation of point clouds has been studied under a variety of scenarios. However, the segmentation of scanned point clouds for a clustered indoor scene remains significantly challenging due to noisy and incomplete data, as well as scene complexity. Based on the observation that objects in an indoor scene vary largely in scale but are typically supported by planes, we propose a co-segmentation approach...
