  title = {Ten years of pedestrian detection, what have we learned?},
  booktitle = {ECCV, CVRSUAD workshop},

}

We review and discuss the 40+ detectors currently present in the Caltech pedestrian detection benchmark. We identify the strategies that have paid-off, and the ones that still have to show their promise.
By combining existing approaches we study their complementarity and report the current best known performance on the challenging Caltech-USA dataset.

How good are detection proposals, really?

  booktitle = {BMVC},
  year = {2014}
}

Detection proposals allow to avoiding exhaustive sliding window search across images, while keeping high detection quality. We provide an in depth analysis of proposal methods regarding recall, repeatability, and impact on DPM detector performance.
Our findings show common weaknesses of existing methods, and provide insights to choose the most adequate method for different settings.

  title = {Face detection without bells and whistles},
  booktitle = {ECCV},
  year = {2014}
}

We present two surprising new face detection results: one using a vanilla deformable part model, and the other using only rigid templates (similar to Viola&Jones' detector).
Both of these reach top performance, improving over commercial and research systems.
We also discuss issues with existing evaluation benchmarks and propose an improved evaluation procedure.

Handling occlusions with franken-classifiers

  title = {Handling Occlusions with Franken-classifiers},
  booktitle = {ICCV},
  year = {2013}
}

Detecting partially occluded pedestrians is challenging.
Here we study why our classifier performs poorly under occlusion and we show that using a set of occlusion specific classifiers can significantly improve detection quality. Our proposed franken-classifiers obtain sub-linear grows in training and testing time, while keeping high detection quality.

Seeking the strongest rigid detector

  title = {Seeking the strongest rigid detector},
  booktitle = {CVPR},
  year = {2013}
}

Previous work to boost detection quality explored using non-linear SVMs, more sophisticated features, geometric priors, motion information, deformable models, or deeper architectures. We use none of these.
Using a single rigid classifier per candidate detection window we reach or improve state-of-the-art performance for pedestrian detection on INRIA, ETH and Caltech USA datasets.

  title = {Traffic Sign Recognition - How far are we from the solution?},
  booktitle = {ICJNN},

}

We show that, without any application specific modification, existing methods for pedestrian detection and face recognition; can reach performances in the range of 95%∼99% of the perfect solution on current traffic sign datasets.

This work was one of the winners of the german traffic sign detection benchmark, see details in related publication.

Fast stixels estimation for fast pedestrian detection

ECCV 2012, CVVT workshop
Selected best paper of the workshop.

  title = {Fast stixels estimation for fast pedestrian detection},
  booktitle = {ECCV, CVVT workshop},
  year = {2012}
}

We revisit the stixel computation method.
Stixels computation now reaches 200 Hz (300 Hz latest version), and we can detect pedestrians at the record speed of 165 Hz (with state of the art quality).

Pedestrian detection at 100 frames per second

  title = {Pedestrian detection at 100 frames per second},

  year = {2012}
}

We propose a new detector that improves both speed and quality over state-of-the-art single part detectors. We reach 50 Hz in monocular setup, and 135 Hz when using stixels on a street scene (including the stereo processing time).
