Improving the Robustness of 3D Human Pose Estimation: A Benchmark and Learning from Noisy Input

no code implementations11 Dec 2023 Trung-Hieu Hoang, Mona Zehni, Huy Phan, Duc Minh Vo, Minh N. Do

We observe the poor generalization of state-of-the-art 3D pose lifters in the presence of corruption and establish two techniques to tackle this issue.

Orthogonal Matrix Retrieval with Spatial Consensus for 3D Unknown-View Tomography

1 code implementation6 Jul 2022 Shuai Huang, Mona Zehni, Ivan Dokmanić, Zhizhen Zhao

Unknown-view tomography (UVT) reconstructs a 3D density map from its 2D projections at unknown, random orientations.

Towards a Comprehensive Solution for a Vision-based Digitized Neurological Examination

no code implementations15 May 2022 Trung-Hieu Hoang, Mona Zehni, Huaijin Xu, George Heintz, Christopher Zallek, Minh N. Do

In this paper, we propose an accessible vision-based exam and documentation solution called Digitized Neurological Examination (DNE) to expand exam biomarker recording options and clinical applications using a smartphone/tablet.

An Adversarial Learning Based Approach for Unknown View Tomographic Reconstruction

no code implementations23 Aug 2021 Mona Zehni, Zhizhen Zhao

The goal of 2D tomographic reconstruction is to recover an image given its projections from various views.

Joint Learning of Portrait Intrinsic Decomposition and Relighting

no code implementations22 Jun 2021 Mona Zehni, Shaona Ghosh, Krishna Sridhar, Sethu Raman

To solve this ill-posed problem from single image, state-of-the-art methods in shape from shading mostly resort to supervised training on all the components on either synthetic or real datasets.

DeepQAMVS: Query-Aware Hierarchical Pointer Networks for Multi-Video Summarization

no code implementations13 May 2021 Safa Messaoud, Ismini Lourentzou, Assma Boughoula, Mona Zehni, Zhizhen Zhao, ChengXiang Zhai, Alexander G. Schwing

The recent growth of web video sharing platforms has increased the demand for systems that can efficiently browse, retrieve and summarize video content.

MSR-GAN: Multi-Segment Reconstruction via Adversarial Learning

1 code implementation18 Feb 2021 Mona Zehni, Zhizhen Zhao

We formulate MSR as a distribution matching problem where the goal is to recover the signal and the probability distribution of the segments such that the distribution of the generated measurements following a known forward model is close to the real observations.

UVTomo-GAN: An adversarial learning based approach for unknown view X-ray tomographic reconstruction

1 code implementation9 Feb 2021 Mona Zehni, Zhizhen Zhao

To accommodate this, we use Gumbel-softmax approximation of samples from categorical distribution to approximate the generator's loss as a function of the unknown image and the projection distribution.

Geometric Invariants for Sparse Unknown View Tomography

1 code implementation25 Nov 2018 Mona Zehni, Shuai Huang, Ivan Dokmanić, Zhizhen Zhao

For a point source model, we show that these features reveal geometric information about the model such as the radial and pairwise distances.

Multi-Segment Reconstruction Using Invariant Features

1 code implementation25 Feb 2018 Mona Zehni, Minh N. Do, Zhizhen Zhao

Instead of trying to locate the segment within the sequence through pair-wise matching, we propose a new approach that uses shift-invariant features to estimate both the underlying signal and the distribution of the positions of the segments.
