Polarimetric PatchMatch Multi-View Stereo

no code implementations11 Nov 2023 Jinyu Zhao, Jumpei Oishi, Yusuke Monno, Masatoshi Okutomi

PatchMatch Multi-View Stereo (PatchMatch MVS) is one of the popular MVS approaches, owing to its balanced accuracy and efficiency.

We then refine the initial model by optimizing photometric rendering errors and polarimetric errors using multi-view RGB, AoP, and DoP images, where we propose a novel polarimetric cost function that enables an effective constraint on the estimated surface normal of each vertex, while considering four possible ambiguous azimuth angles revealed from the AoP measurement.

Unsupervised Embedding of Hierarchical Structure in Euclidean Space

1 code implementation30 Oct 2020 Jinyu Zhao, Yi Hao, Cyrus Rashtchian

To learn the embedding, we revisit using a variational autoencoder with a Gaussian mixture prior, and we show that rescaling the latent space embedding and then applying Ward's linkage-based algorithm leads to improved results for both dendrogram purity and the Moseley-Wang cost function.

A polarization camera has great potential for 3D reconstruction since the angle of polarization (AoP) of reflected light is related to an object's surface normal.

COVID-CT-Dataset: A CT Scan Dataset about COVID-19

19 code implementations30 Mar 2020 Xingyi Yang, Xuehai He, Jinyu Zhao, Yichen Zhang, Shanghang Zhang, Pengtao Xie

Using this dataset, we develop diagnosis methods based on multi-task learning and self-supervised learning, that achieve an F1 of 0. 90, an AUC of 0. 98, and an accuracy of 0. 89.
