Hierarchical Gaussian Mixture Normalizing Flow Modeling for Unified Anomaly Detection

ECCV 2024poster

"Unified anomaly detection (AD) is one of the most valuable challenges for anomaly detection, where one unified model is trained with normal samples from multiple classes with the objective to detect anomalies in these classes. For such a challenging task, popular normalizing flow (NF) based AD meth…

Adaptive Semantic Fusion Framework for Unsupervised Monocular Depth Estimation

ICASSP 2023accepted

Unsupervised monocular depth estimation plays an important role in autonomous driving, and has been received considerable research attention in recent years. Nevertheless, numerous existing methods relying on photometric consistency are excessively susceptible to variations in illumination and suffe…

Explicit Boundary Guided Semi-Push-Pull Contrastive Learning for Supervised Anomaly Detection

CVPR 2023poster

Most anomaly detection (AD) models are learned using only normal samples in an unsupervised way, which may result in ambiguous decision boundary and insufficient discriminability. In fact, a few anomaly samples are often available in real-world applications, the valuable knowledge of known anomalies…

Focus the Discrepancy: Intra- and Inter-Correlation Learning for Image Anomaly Detection

ICCV 2023poster

Humans recognize anomalies through two aspects: larger patch-wise representation discrepancies and weaker patch-to-normal-patch correlations. However, the previous AD methods didn't sufficiently combine the two complementary aspects to design AD models. To this end, we find that Transformer can idea…

One-for-All: Proposal Masked Cross-Class Anomaly Detection

AAAI 2023technical

One of the most challenges for anomaly detection (AD) is how to learn one unified and generalizable model to adapt to multi-class especially cross-class settings: the model is trained with normal samples from seen classes with the objective to detect anomalies from both seen and unseen classes. In t…

Out-of-Distribution Identification: Let Detector Tell Which I Am Not Sure

ECCV 2022poster

"The superior performance of object detectors is often established under the condition that the test samples are in the same distribution as the training data. However, in most practical applications, out-of-distribution (OOD) instances are inevitable and usually lead to detection uncertainty. In th…

You Only Infer Once: Cross-Modal Meta-Transfer for Referring Video Object Segmentation

AAAI 2022technical

We present YOFO (You Only inFer Once), a new paradigm for referring video object segmentation (RVOS) that operates in an one-stage manner. Our key insight is that the language descriptor should serve as target-specific guidance to identify the target object, while a direct feature fusion of image an…
