What is Learned in Deep Uncalibrated Photometric Stereo?

no code implementations ECCV 2020 Guan-Ying Chen, Michael Waechter, Boxin Shi, Kwan-Yee K. Wong, Yasuyuki Matsushita

Based on this insight, we propose a guided calibration network, named GCNet, that explicitly leverages object shape and shading information for improved lighting estimation.

Deep Photometric Stereo for Non-Lambertian Surfaces

1 code implementation26 Jul 2020 Guan-Ying Chen, Kai Han, Boxin Shi, Yasuyuki Matsushita, Kwan-Yee K. Wong

To deal with the uncalibrated scenario where light directions are unknown, we introduce a new convolutional network, named LCNet, to estimate light directions from input images.

ET-USB: Transformer-Based Sequential Behavior Modeling for Inbound Customer Service

no code implementations20 Dec 2019 Ta-Chun Su, Guan-Ying Chen

Therefore, we created a new approach, ET-USB, that incorporates users' sequential and nonsequential features; we apply the powerful Transformer encoder, a self-attention network model, to capture the information underlying user behavior sequences.

Learning Transparent Object Matting

1 code implementation25 Jul 2019 Guan-Ying Chen, Kai Han, Kwan-Yee K. Wong

In this paper, we formulate transparent object matting as a refractive flow estimation problem, and propose a deep learning framework, called TOM-Net, for learning the refractive flow.
