IDMS: Instance Depth for Multi-scale Monocular 3D Object Detection

no code implementations3 Dec 2022 Chao Hu, Liqiang Zhu, Weibing Qiu, Weijie Wu

Firstly, to enhance the model's processing ability for different scale targets, a multi-scale perception module based on dilated convolution is designed, and the depth features containing multi-scale information are re-refined from both spatial and channel directions considering the inconsistency between feature maps of different scales.

Pedestrian Spatio-Temporal Information Fusion For Video Anomaly Detection

no code implementations18 Nov 2022 Chao Hu, Liqiang Zhu

Aiming at the problem that the current video anomaly detection cannot fully use the temporal information and ignore the diversity of normal behavior, an anomaly detection method is proposed to integrate the spatiotemporal information of pedestrians.

Efficient Unsupervised Video Object Segmentation Network Based on Motion Guidance

no code implementations10 Nov 2022 Chao Hu, Liqiang Zhu

Then, the semantic features of the motion representation are obtained through the local attention mechanism in the motion guidance module to obtain the high-level semantic features of the appearance representation.

Spatio-Temporal-based Context Fusion for Video Anomaly Detection

no code implementations18 Oct 2022 Chao Hu, Weibin Qiu, Weijie Wu, Liqiang Zhu

Motion features are used multiple targets in the video frame to construct spatial context simultaneously, re-encoding the target appearance and motion features, and finally reconstructing the above features through the spatio-temporal dual-stream network, and using the reconstruction error to represent the abnormal score.

Reliable Identification of Redundant Kernels for Convolutional Neural Network Compression

no code implementations10 Dec 2018 Wei Wang, Liqiang Zhu

To compress deep convolutional neural networks (CNNs) with large memory footprint and long inference time, this paper proposes a novel pruning criterion using layer-wised Ln-norm of feature maps.
