QuickPIV: Efficient 3D particle image velocimetry software applied to quantifying cellular migration during embryogenesis

Marc Pereyra, Armin Drusko, Franziska Krämer, Frederic Strobl, Ernst H. K. Stelzer, Franziska Matthäus
2021 BMC Bioinformatics  
We show normalized squared error cross-correlation to be especially accurate in detecting translations in non-segmentable biological image data.  ...  Currently, quickPIV offers efficient 2D and 3D PIV analyses featuring zero-normalized and normalized squared error cross-correlations, sub-pixel/voxel approximation, and multi-pass.  ...  These biases are completely avoided by using NSQECC, which detects the underlying translation with 100% accuracy given a sufficiently large search margin (see Figure S1 ).  ...

Input-level Inductive Biases for 3D Reconstruction [article]

Wang Yifan, Carl Doersch, Relja Arandjelović, João Carreira, Andrew Zisserman
2022 arXiv   pre-print
In this paper we tackle 3D reconstruction using a domain agnostic architecture and study how instead to inject the same type of inductive biases directly as extra inputs to the model.  ...  In particular we study how to encode cameras, projective ray incidence and epipolar geometry as model inputs, and demonstrate competitive multi-view depth estimation performance on multiple benchmarks.  ...  We thank Yi Yang for providing advice regarding data processing and Jean-Baptiste Alayrac for his help with the training pipeline.  ...

Synchronization and Self-Calibration for Helmet-Held Consumer Cameras, Applications to Immersive 3D Modeling and 360 Video

Maxime Lhuillier, Thanh-Tin Nguyen
2015 2015 International Conference on 3D Vision  
We experiment both synchronization and self-calibration on four GoPro cameras mounted on a helmet, such that the resulting multi-camera is assumed to be central and provides a 360 degree field-of-view  ...  Our assumptions are easy to meet in practice: the cameras have the same setting (frequency, image resolution, field-of-view, roughly equiangular).  ...  The registration is defined by rotation R, which maps one ray set to another (no translation since the calibrations are central in our paper).  ...
