Full or Weak Annotations? An Adaptive Strategy for Budget-Constrained Annotation Campaigns

CVPR 2023poster

Annotating new datasets for machine learning tasks is tedious, time-consuming, and costly. For segmentation applications, the burden is particularly high as manual delineations of relevant image content are often extremely expensive or can only be done by experts with domain-specific knowledge. Than…

Logical Implications for Visual Question Answering Consistency

CVPR 2023poster

Despite considerable recent progress in Visual Question Answering (VQA) models, inconsistent or contradictory answers continue to cast doubt on their true reasoning capabilities. However, most proposed methods use indirect strategies or strong assumptions on pairs of questions and answers to enforce…

Stochastic Segmentation with Conditional Categorical Diffusion Models

ICCV 2023poster

Semantic segmentation has made significant progress in recent years thanks to deep neural networks, but the common objective of generating a single segmentation output that accurately matches the image's content may not be suitable for safety-critical domains such as medical diagnostics and autonomo…

Data Invariants to Understand Unsupervised Out-of-Distribution Detection

ECCV 2022poster

"Unsupervised out-of-distribution (U-OOD) detection has recently attracted much attention due to its importance in mission-critical systems and broader applicability over its supervised counterpart. Despite this increased attention, U-OOD methods suffer from important shortcomings. By performing a l…

Beyond the Pixel-Wise Loss for Topology-Aware Delineation

CVPR 2018poster

Delineation of curvilinear structures is an important problem in Computer Vision with multiple practical applications. With the advent of Deep Learning, many current approaches on automatic delineation have focused on finding more powerful deep architectures, but have continued using the habitual pi…
