By decomposing the visual tracking task into two subproblems as classification for pixel category and regression object bounding box at this pixel, we propose a novel fully convolutional Siamese network to solve end-to-end in per-pixel manner. The proposed framework SiamCAR consists of simple subnetworks: one subnetwork feature extraction classification-regression prediction. Different from state-of-the-art trackers like Siamese-RPN, SiamRPN++ SPM, which are based on region proposal, is both...

Siamese network based trackers formulate the visual tracking task as a similarity matching problem. Almost all popular realize learning via convolutional feature cross-correlation between target branch and search branch. However, since size of region needs to be pre-fixed, these base methods suffer from either reserving much adverse background information or missing great deal foreground information. Moreover, global be-tween also largely neglects structure part-level information.In this...

Point cloud completion referring to completing 3D shapes from partial point clouds is a fundamental problem for analysis tasks. Benefiting the development of deep neural networks, researches on have made great progress in recent years. However, explicit local region partition like kNNs involved existing methods makes them sensitive density distribution clouds. Moreover, it serves limited receptive fields that prevent capturing features long-range context information. To solve problems, we...

Abstract Visual tracking of generic objects is one the fundamental but challenging problems in computer vision. Here, we propose a novel fully convolutional Siamese network to solve visual by directly predicting target bounding box an end-to-end manner. We first reformulate task as two subproblems: classification problem for pixel category prediction and regression object status estimation at this pixel. With decomposition, design simple yet effective architecture based framework, termed...

For a given data set, exploring their multi-view instances under clustering framework is practical way to boost the performance. This because that each view might reflect partial information for existing data. Furthermore, due noise and other impact factors, these from different views will enhance mining of real structure feature within set. In this paper, we propose multiple kernel spectral algorithm through on By combining matrix learning optimization into one process framework, can...

Cerebral ischaemia-reperfusion injury (CIRI) could worsen the inflammatory response and oxidative stress in brain tissue. According to previous studies, ferulic acid methyl ester (FAME), as extract with strongest comprehensive activity traditional Chinese medicine Huang Hua oil dot herb, has significant anti-oxidative neuroprotective functions, can effectively alleviate CIRI, but its mechanism of action is still unclear.

Siamese-network-based trackers convert the general object tracking as a similarity matching task between template and search region. Using convolutional feature cross correlation (Xcorr) for matching, large number of Siamese are proposed achieved great success. However, due to predefined size target feature, these suffer from either retaining much background information or losing important foreground information. Moreover, global region also largely neglects part-level structural contextual...
