Quantile-Based Maximum Likelihood Training for Outlier Detection

AAAI 2024technical

Discriminative learning effectively predicts true object class for image classification. However, it often results in false positives for outliers, posing critical concerns in applications like autonomous driving and video surveillance systems. Previous attempts to address this challenge involved tr…

Normalizing Flow Based Feature Synthesis for Outlier-Aware Object Detection

CVPR 2023highlight

Real-world deployment of reliable object detectors is crucial for applications such as autonomous driving. However, general-purpose object detectors like Faster R-CNN are prone to providing overconfident predictions for outlier objects. Recent outlier-aware object detection approaches estimate the d…

Reinforced Feature Points: Optimizing Feature Detection and Description for a High-Level Task

CVPR 2020oral

We address a core problem of computer vision: Detection and description of 2D feature points for image matching. For a long time, hand-crafted designs, like the seminal SIFT algorithm, were unsurpassed in accuracy and efficiency. Recently, learned feature detectors emerged that implement detection a…

DSAC - Differentiable RANSAC for Camera Localization

CVPR 2017oral

RANSAC is an important algorithm in robust optimization and a central building block for many computer vision applications. In recent years, traditionally hand-crafted pipelines have been replaced by deep learning pipelines, which can be trained in an end-to-end fashion. However, RANSAC has so far n…

Global Hypothesis Generation for 6D Object Pose Estimation

CVPR 2017spotlight

This paper addresses the task of estimating the 6D-pose of a known 3D object from a single RGB-D image. Most modern approaches solve this task in three steps: i) compute local features; ii) generate a pool of pose-hypotheses; iii) select and refine a pose from the pool. This work focuses on the seco…

Uncertainty-Driven 6D Pose Estimation of Objects and Scenes From a Single RGB Image

CVPR 2016poster

In recent years, the task of estimating the 6D pose of object instances and complete scenes, i.e. camera localization, from a single input image has received considerable attention. Consumer RGB-D cameras have made this feasible, even for difficult, texture-less objects and scenes. In this work, we…

Learning Analysis-by-Synthesis for 6D Pose Estimation in RGB-D Images

ICCV 2015poster

Analysis-by-synthesis has been a successful approach for many tasks in computer vision, such as 6D pose estimation of an object in an RGB-D image which is the topic of this work. The idea is to compare the observation with the output of a forward process, such as a rendered image of the object of in…
