The large availability of depth sensors provides valuable complementary information for salient object detection (SOD) in RGBD images. However, due to the inherent difference between RGB and information, extracting features from channel using ImageNet pre-trained backbone models fusing them with directly are sub-optimal. In this paper, we utilize contrast prior, which used be a dominant cue none deep learning based SOD approaches, into CNNs-based architecture enhance information. enhanced...

Extracting road graphs from aerial images automatically is more efficient and costs less than field acquisition. This can be done by a post-processing step that vectorizes segmentation predicted CNN, but imperfect predictions will result in with low connectivity. On the other hand, iterative next move exploration could construct better connectivity, often focuses on local information does not provide precise alignment real road. To enhance connectivity while maintaining between graph road,...

Abstract Perineuronal nets (PNNs) which mostly surround the parvalbumin (PV) neurons, have been shown to play critical roles in neural plasticity. Recently, PNNs regulate fear‐associated memory, but molecular mechanism is still unclear. In this study, we found that removal of vivo using chondroitinase ABC (ChABC) injection resulted reduced firing rate PV neurons and decreased inhibitory synaptic transmission both excitatory CA1 hippocampus. Interestingly, altered appears be mediated by...

Directly learning features from the point cloud has become an active research direction in 3D understanding. Existing learning-based methods usually construct local regions and extract corresponding features. However, most of these processes do not adequately take spatial distribution into account, limiting ability to perceive fine-grained patterns. We design a novel Local Spatial Aware (LSA) layer, which can learn generate Distribution Weights (SDWs) hierarchically based on relationship...
