This paper considers metric 3D reconstruction with hierarchical merging. We first describe pairwise matching of images for spanning tree construction. The epipolar constraint is imposed on two related vertices. We then present a partition method to group the images into duplets or triplets for partial reconstruction. A robust hierarchical scheme that merges partial reconstruction together is used...
This paper presents a feature recognition method based on randomized trees. We aim to improve the performance of Lepetit's work, whose actual results are very sensitive to large changes of viewpoint due to its limited ability of samples synthesizing and learning. We propose an approach to alleviate its limitation, which simulates the image appearance changes under actual viewpoint changes by applying...
