Saliency Detection via Nonlocal L_0 Minimization
In this paper, by observing the intrinsic sparsity of saliency map for the image, we propose a novel nonlocal L0 minimization framework to extract the sparse geometric structure of the saliency maps for the natural images. Specifically, we first propose to use the k-nearest neighbors of superpixels to construct a graph in the feature space. The novel L0-regularized nonlocal minimization model i...
متن کاملSaliency-Based Deformable Model for Pedestrian Detection
Pedestrian detection, which is to identify category (pedestrian) of object and give the position information in the image, is an important and yet challenging task due to the intra-class variation of pedestrians in clothing and articulation. Previous researches mainly focus on feature extraction and sliding window, where the former aims to find robust feature representation while the latter see...
متن کاملA New Detection Model for Saliency Map
Visual attention is a mechanism which filters out redundant visual information and focus on the most relevant parts when observing an image, many bottom-up computational models of visual attention have been devised to get the saliency map for an image. In this paper, a new visual attention model is proposed. Based on the experimental results obtained in this study, as compared with existing bot...
متن کاملExistence for Nonlocal Variational Problems in Peridynamics
We present an existence theory based on minimization of the nonlocal energies appearing in peridynamics, which is a nonlocal continuum model in solid mechanics that avoids the use of deformation gradients. We employ the direct method of the calculus of variations in order to find minimizers of the energy of a deformation. Lower semicontinuity is proved under a weaker condition than convexity, w...
