Pixel-Pair Occlusion Relationship Map (P2ORM): Formulation, Inference & Application

no code implementations ECCV 2020 Xuchong Qiu, Yang Xiao, Chaohui Wang, Renaud Marlet

Inference & Application","We formalize concepts around geometric occlusion in 2D images (i. e., ignoring semantics), and propose a novel unified formulation of both occlusion boundaries and occlusion orientations via a pixel-pair occlusion relation.

Pixel-Pair Occlusion Relationship Map(P2ORM): Formulation, Inference & Application

1 code implementation23 Jul 2020 Xuchong Qiu, Yang Xiao, Chaohui Wang, Renaud Marlet

The former provides a way to generate large-scale accurate occlusion datasets while, based on the latter, we propose a novel method for task-independent pixel-level occlusion relationship estimation from single images.

Robust Angular Local Descriptor Learning

1 code implementation21 Jan 2019 Yanwu Xu, Mingming Gong, Tongliang Liu, Kayhan Batmanghelich, Chaohui Wang

In recent years, the learned local descriptors have outperformed handcrafted ones by a large margin, due to the powerful deep convolutional neural network architectures such as L2-Net [1] and triplet based metric learning [2].

MoE-SPNet: A Mixture-of-Experts Scene Parsing Network

no code implementations19 Jun 2018 Huan Fu, Mingming Gong, Chaohui Wang, DaCheng Tao

In the proposed networks, different levels of features at each spatial location are adaptively re-weighted according to the local structure and surrounding contextual information before aggregation.

Deep Ordinal Regression Network for Monocular Depth Estimation

5 code implementations CVPR 2018 Huan Fu, Mingming Gong, Chaohui Wang, Kayhan Batmanghelich, DaCheng Tao

These methods model depth estimation as a regression problem and train the regression networks by minimizing mean squared error, which suffers from slow convergence and unsatisfactory local solutions.

A Compromise Principle in Deep Monocular Depth Estimation

no code implementations28 Aug 2017 Huan Fu, Mingming Gong, Chaohui Wang, DaCheng Tao

However, we find that training a network to predict a high spatial resolution continuous depth map often suffers from poor local solutions.

Perceptual Adversarial Networks for Image-to-Image Transformation

2 code implementations28 Jun 2017 Chaoyue Wang, Chang Xu, Chaohui Wang, DaCheng Tao

The proposed PAN consists of two feed-forward convolutional neural networks (CNNs), the image transformation network T and the discriminative network D. Through combining the generative adversarial loss and the proposed perceptual adversarial loss, these two networks can be trained alternately to solve image-to-image transformation tasks.

Tag Disentangled Generative Adversarial Networks for Object ImageRe-rendering

no code implementations International Joint Conference on Artificial Intelligence 2017 Chaoyue Wang, Chaohui Wang, Chang Xu, DaCheng Tao

The whole framework consists of a disentangling network, a generative network, a tag mapping net, and a discriminative network, which are trained jointly based on a given set of images that are complete/partially tagged(i. e., supervised/semi-supervised setting).

Scene-Domain Active Part Models for Object Representation

no code implementations ICCV 2015 Zhou Ren, Chaohui Wang, Alan L. Yuille

In this paper, we are interested in enhancing the expressivity and robustness of part-based models for object representation, in the common scenario where the training data are based on 2D images.

MUlti-Store Tracker (MUSTer): A Cognitive Psychology Inspired Approach to Object Tracking

no code implementations CVPR 2015 Zhibin Hong, Zhe Chen, Chaohui Wang, Xue Mei, Danil Prokhorov, DaCheng Tao

Variations in the appearance of a tracked object, such as changes in geometry/photometry, camera viewpoint, illumination, or partial occlusion, pose a major challenge to object tracking.
