Pseudocode Yes Algorithm 1 HOSVD-HT
Open Source Code Yes We include our code in the following github repository: Trifocal Sync.
Open Datasets Yes We conduct experiments of Algorithm 2 on two benchmark real datasets, the EPFL datasets [42] and the Photo Tourism datasets [11].
Dataset Splits No The paper describes the use of 'EPFL datasets' and 'Photo Tourism datasets' and discusses experimental procedures such as feature detection, matching, and synchronization. However, it does not provide explicit details on how these datasets were split into training, validation, and test sets, or if standard predefined splits were used with citations.
Hardware Specification Yes We test our full pipeline on two EPFL datasets on a personal machine with 2 GHz Intel Core i5 with 4 cores and 16GB of memory.
Software Dependencies No The paper mentions specific software tools like 'Glue Stick [45]' and 'GC-ransac [49]' but does not provide their specific version numbers or other software dependencies with versioning (e.g., Python, PyTorch, etc.).
Experiment Setup Yes We apply STE from [41] to find 40% of the correspondences as inliers, then use at most 30 inlier point correspondences to linearly estimate the trifocal tensor. To refine the estimates, we apply bundle adjustment on the inliers and delete triplets with reprojection error larger than 1 pixel.
