URS-NeRF: Unordered Rolling Shutter Bundle Adjustment for Neural Radiance Fields

no code implementations15 Mar 2024 Bo Xu, Ziao Liu, Mengqi Guo, Jiancheng Li, Gim Hee Lee

We propose a novel rolling shutter bundle adjustment method for neural radiance fields (NeRF), which utilizes the unordered rolling shutter (RS) images to obtain the implicit 3D representation.

Unsupervised Part Discovery via Feature Alignment

no code implementations1 Dec 2020 Mengqi Guo, Yutong Bai, Zhishuai Zhang, Adam Kortylewski, Alan Yuille

Specifically, given a training image, we find a set of similar images that show instances of the same object category in the same pose, through an affine alignment of their corresponding feature maps.
