Texture+depth (RGBD) images provide information about the geometry of a scene, which could help improve current image matching performance, e.g., in presence of large viewpoint changes. While depth has been mainly used for processing keypoint descriptors, in this paper we focus on the keypoint detection problem. In order to produce a computationally efficient viewpoint-covariant multiscale representation,...
The goal of this paper is to assess whether existing solutions to expand low dynamic range (LDR) still images to high dynamic range (HDR) displays can apply to moving pictures. To this end, we conduct a subjective quality assessment test on four state-of-the-art expansion operators, using high-quality input LDR content. Our results show that, perhaps surprisingly, no temporal artifacts, such as flickering...
