LEPARD: Learning Explicit Part Discovery for 3D Articulated Shape Reconstruction

NeurIPS 2023poster

Reconstructing the 3D articulated shape of an animal from a single in-the-wild image is a challenging task. We propose LEPARD, a learning-based framework that discovers semantically meaningful 3D parts and reconstructs 3D shapes in a part-based manner. This is advantageous as 3D parts are robust to…

Learning Articulated Shape With Keypoint Pseudo-Labels From Web Images

CVPR 2023poster

This paper shows that it is possible to learn models for monocular 3D reconstruction of articulated objects (e.g. horses, cows, sheep), using as few as 50-150 images labeled with 2D keypoints. Our proposed approach involves training category-specific keypoint estimators, generating 2D keypoint pseud…

Exploiting Unlabeled Data with Vision and Language Models for Object Detection

ECCV 2022poster

"Building robust and generic object detection frameworks requires scaling to larger label spaces and bigger training datasets. However, it is prohibitively costly to acquire annotations for thousands of categories at a large scale. We propose a novel method that leverages the rich semantics availabl…

Dual Projection Generative Adversarial Networks for Conditional Image Generation

ICCV 2021poster

Conditional Generative Adversarial Networks (cGANs) extend the standard unconditional GAN framework to learning joint data-label distributions from samples, and have been established as powerful generative models capable of generating high-fidelity imagery. A challenge of training such a model lies…
