Multilevel Saliency-Guided Self-Supervised Learning for Image Anomaly Detection

no code implementations30 Nov 2023 Jianjian Qin, Chunzhi Gu, Jun Yu, Chao Zhang

To fully exploit saliency guidance, on each map, we select a pixel pair from the cluster with the highest centroid saliency to form a patch pair.

Image-Pointcloud Fusion based Anomaly Detection using PD-REAL Dataset

no code implementations7 Nov 2023 Jianjian Qin, Chunzhi Gu, Jun Yu, Chao Zhang

We present PD-REAL, a novel large-scale dataset for unsupervised anomaly detection (AD) in the 3D domain.

Orientation-Aware Leg Movement Learning for Action-Driven Human Motion Prediction

no code implementations23 Oct 2023 Chunzhi Gu, Chao Zhang, Shigeru Kuriyama

Specifically, we follow a two-stage forecasting strategy by first employing the motion diffusion model to generate the target motion with a specified future action, and then producing the in-betweening to smoothly connect the observation and prediction to eventually address motion prediction.

A Multi-In and Multi-Out Dendritic Neuron Model and its Optimization

no code implementations14 Sep 2023 Yu Ding, Jun Yu, Chunzhi Gu, Shangce Gao, Chao Zhang

Recently, a novel mathematical ANN model, known as the dendritic neuron model (DNM), has been proposed to address nonlinear problems by more accurately reflecting the structure of real neurons.

Teacher-Student Network for 3D Point Cloud Anomaly Detection with Few Normal Samples

no code implementations31 Oct 2022 Jianjian Qin, Chunzhi Gu, Jun Yu, Chao Zhang

Moreover, our method only requires very few normal samples to train the student network due to the teacher-student distillation mechanism.

Learning Disentangled Representations for Controllable Human Motion Prediction

no code implementations4 Jul 2022 Chunzhi Gu, Jun Yu, Chao Zhang

Specifically, the inductive bias imposed by the extra CVAE path encourages two latent variables in two paths to respectively govern separate representations for each partial-body motion.

Learning to Predict Diverse Human Motions from a Single Image via Mixture Density Networks

no code implementations13 Sep 2021 Chunzhi Gu, Yan Zhao, Chao Zhang

Human motion prediction, which plays a key role in computer vision, generally requires a past motion sequence as input.

Example-based Color Transfer with Gaussian Mixture Modeling

no code implementations31 Aug 2020 Chunzhi Gu, Xuequan Lu, Chao Zhang

In particular, we relate the transferred image with the example image under the Gaussian Mixture Model (GMM) and regard the transferred image color as the GMM centroids.

Blur Removal via Blurred-Noisy Image Pair

no code implementations26 Mar 2019 Chunzhi Gu, Xuequan Lu, Ying He, Chao Zhang

Complex blur such as the mixup of space-variant and space-invariant blur, which is hard to model mathematically, widely exists in real images.
