Many dense 3D point clouds have been exploited to represent visual objects instead of traditional images or videos. To evaluate the perceptual quality various clouds, in this letter, we propose a novel and efficient Reduced-Reference metric for which is based on Content-oriented sAliency Projection (RR-CAP). Specifically, make first attempt simplify reference distorted into projected saliency m...

An algorithm is described which rapidly veri es the potential rigidity of three dimensional point correspondences from a pair of two dimensional views under perspective projection. The output of the algorithm is a simple yes or no answer to the question \Could these corresponding points from two views be the projection of a rigid con guration?" Potential applications include 3D object recogniti...

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not.
