FvOR: Robust Joint Shape and Pose Optimization for Few-view Object Reconstruction

1 code implementation CVPR 2022 Zhenpei Yang, Zhile Ren, Miguel Angel Bautista, Zaiwei Zhang, Qi Shan, QiXing Huang

In this paper, we present FvOR, a learning-based object reconstruction method that predicts accurate 3D models given a few images with noisy input poses.

VideoPose: Estimating 6D object pose from videos

no code implementations20 Nov 2021 Apoorva Beedu, Zhile Ren, Varun Agrawal, Irfan Essa

We introduce a simple yet effective algorithm that uses convolutional neural networks to directly estimate object poses from videos.

Semantic MapNet: Building Allocentric Semantic Maps and Representations from Egocentric Views

1 code implementation2 Oct 2020 Vincent Cartillier, Zhile Ren, Neha Jain, Stefan Lee, Irfan Essa, Dhruv Batra

We study the task of semantic mapping - specifically, an embodied agent (a robot or an egocentric AI assistant) is given a tour of a new environment and asked to build an allocentric top-down semantic map ("what is where?")

Cross-channel Communication Networks

1 code implementation NeurIPS 2019 Jianwei Yang, Zhile Ren, Chuang Gan, Hongyuan Zhu, Devi Parikh

Convolutional neural networks process input data by sending channel-wise feature response maps to subsequent layers.

Clouds of Oriented Gradients for 3D Detection of Objects, Surfaces, and Indoor Scene Layouts

no code implementations11 Jun 2019 Zhile Ren, Erik B. Sudderth

We develop new representations and algorithms for three-dimensional (3D) object detection and spatial layout prediction in cluttered indoor scenes.

Embodied Visual Recognition

no code implementations9 Apr 2019 Jianwei Yang, Zhile Ren, Mingze Xu, Xinlei Chen, David Crandall, Devi Parikh, Dhruv Batra

Passive visual systems typically fail to recognize objects in the amodal setting where they are heavily occluded.

A Fusion Approach for Multi-Frame Optical Flow Estimation

2 code implementations23 Oct 2018 Zhile Ren, Orazio Gallo, Deqing Sun, Ming-Hsuan Yang, Erik B. Sudderth, Jan Kautz

To date, top-performing optical flow estimation methods only take pairs of consecutive frames into account.

3D Object Detection With Latent Support Surfaces

no code implementations CVPR 2018 Zhile Ren, Erik B. Sudderth

We develop a 3D object detection algorithm that uses latent support surfaces to capture contextual relationships in indoor scenes.

Cascaded Scene Flow Prediction using Semantic Segmentation

no code implementations26 Jul 2017 Zhile Ren, Deqing Sun, Jan Kautz, Erik B. Sudderth

Given two consecutive frames from a pair of stereo cameras, 3D scene flow methods simultaneously estimate the 3D geometry and motion of the observed scene.

Three-Dimensional Object Detection and Layout Prediction Using Clouds of Oriented Gradients

no code implementations CVPR 2016 Zhile Ren, Erik B. Sudderth

We develop new representations and algorithms for three-dimensional (3D) object detection and spatial layout prediction in cluttered indoor scenes.

Image Segmentation by Cascaded Region Agglomeration

no code implementations CVPR 2013 Zhile Ren, Gregory Shakhnarovich

We propose a hierarchical segmentation algorithm that starts with a very fine oversegmentation and gradually merges regions using a cascade of boundary classifiers.
