HEViTPose: High-Efficiency Vision Transformer for Human Pose Estimation

1 code implementation22 Nov 2023 Chengpeng Wu, Guangxing Tan, Chunyu Li

Comprehensive experiments on two benchmark datasets (MPII and COCO) demonstrate that the small and large HEViTPose models are on par with state-of-the-art models while being more lightweight.

Deep Hyperspectral-Depth Reconstruction Using Single Color-Dot Projection

no code implementations CVPR 2022 Chunyu Li, Yusuke Monno, Masatoshi Okutomi

To jointly reconstruct the depth and the hyperspectral reflectance from a single color-dot image, we propose a novel end-to-end network architecture that effectively incorporates a geometric color-dot pattern loss and a photometric hyperspectral reflectance loss.

Information retrieval for label noise document ranking by bag sampling and group-wise loss

no code implementations12 Mar 2022 Chunyu Li, Jiajia Ding, Xing Hu, Fan Wang

To fit bag sampling well, after query and document are encoded, the global features of each group are extracted by convolutional layer and max-pooling to improve the model's resistance to the impact of labeling noise, finally, calculate the LCE group-wise loss.

Spectral MVIR: Joint Reconstruction of 3D Shape and Spectral Reflectance

no code implementations15 Apr 2021 Chunyu Li, Yusuke Monno, Masatoshi Okutomi

Reconstructing an object's high-quality 3D shape with inherent spectral reflectance property, beyond typical device-dependent RGB albedos, opens the door to applications requiring a high-fidelity 3D model in terms of both geometry and photometry.

Pro-Cam SSfM: Projector-Camera System for Structure and Spectral Reflectance from Motion

no code implementations ICCV 2019 Chunyu Li, Yusuke Monno, Hironori Hidaka, Masatoshi Okutomi

In this paper, we propose a novel projector-camera system for practical and low-cost acquisition of a dense object 3D model with the spectral reflectance property.
