CostFilter-AD: Enhancing Anomaly Detection through Matching Cost Filtering

ICML 2025poster

Unsupervised anomaly detection (UAD) seeks to localize the anomaly mask of an input image with respect to normal samples. Either by reconstructing normal counterparts (reconstruction-based) or by learning an image feature embedding space (embedding-based), existing approaches fundamentally rely on i…

Regret and Cumulative Constraint Violation Analysis for Online Convex Optimization with Long Term Constraints

ICML 2021oral

This paper considers online convex optimization with long term constraints, where constraints can be violated in intermediate rounds, but need to be satisfied in the long run. The cumulative constraint violation is used as the metric to measure constraint violations, which excludes the situation tha…

Light Field Reconstruction Using Deep Convolutional Network on EPI

CVPR 2017poster

In this paper, we take advantage of the clear texture structure of the epipolar plane image (EPI) in the light field data and model the problem of light field reconstruction from a sparse set of views as a CNN-based angular detail restoration on EPI. We indicate that one of the main challenges in sp…
