Reconstructing Evolving Tree Structures in Time Lapse Sequences
Found in: 2014 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
By Przemyslaw Glowacki,Miguel Amavel Pinheiro,Engin Turetken,Raphael Sznitman,Daniel Lebrecht,Jan Kybic,Anthony Holtmaat,Pascal Fua
Issue Date:June 2014
pp. 3035-3042
We propose an approach to reconstructing tree structures that evolve over time in 2D images and 3D image stacks such as neuronal axons or plant branches. Instead of reconstructing structures in each image independently, we do so for all images simultaneous...
 
Active Testing for Face Detection and Localization
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Raphael Sznitman, Bruno Jedynak
Issue Date:October 2010
pp. 1914-1920
We provide a novel search technique which uses a hierarchical model and a mutual information gain heuristic to efficiently prune the search space when localizing faces in images. We show exponential gains in computation over traditional sliding window appr...
 
Non-Rigid Graph Registration using Active Testing Search
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Eduard Serradell,Miguel Pinheiro,Raphael Sznitman,Jan Kybic,Francesc Moreno-Noguer,Pascal Fua
Issue Date:August 2014
pp. 1
We present a new approach for matching sets of branching curvilinear structures that form graphs embedded in R2 or R3 and may be subject to deformations. Unlike earlier methods, ours does not rely on local appearance similarity nor does require a good init...
 
Fast Object Detection with Entropy-Driven Evaluation
Found in: 2013 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
By Raphael Sznitman,Carlos Becker,Francois Fleuret,Pascal Fua
Issue Date:June 2013
pp. 3270-3277
Cascade-style approaches to implementing ensemble classifiers can deliver significant speed-ups at test time. While highly effective, they remain challenging to tune and their overall performance depends on the availability of large validation sets to esti...
