BASE: Probably a Better Approach to Multi-Object Tracking

no code implementations21 Sep 2023 Martin Vonheim Larsen, Sigmund Rolfsjord, Daniel Gusland, Jörgen Ahlberg, Kim Mathiassen

The field of visual object tracking is dominated by methods that combine simple tracking algorithms and ad hoc schemes.

Unsupervised Learning of Anomaly Detection from Contaminated Image Data using Simultaneous Encoder Training

1 code implementation27 May 2019 Amanda Berg, Jörgen Ahlberg, Michael Felsberg

In this work, we evaluate the effects of anomaly contaminations in the training data on state-of-the-art GAN-based anomaly detection methods.

Memory-Efficient Global Refinement of Decision-Tree Ensembles and its Application to Face Alignment

no code implementations27 Feb 2017 Nenad Markuš, Ivan Gogić, Igor S. Pandžić, Jörgen Ahlberg

Ren et al. recently introduced a method for aggregating multiple decision trees into a strong predictor by interpreting a path taken by a sample down each tree as a binary vector and performing linear regression on top of these vectors stacked together.

Constructing Binary Descriptors with a Stochastic Hill Climbing Search

no code implementations20 Jan 2015 Nenad Markuš, Igor S. Pandžić, Jörgen Ahlberg

Binary descriptors of image patches provide processing speed advantages and require less storage than methods that encode the patch appearance with a vector of real numbers.

Fast Localization of Facial Landmark Points

3 code implementations26 Mar 2014 Nenad Markuš, Miroslav Frljak, Igor S. Pandžić, Jörgen Ahlberg, Robert Forchheimer

We describe a method that can accurately estimate the positions of relevant facial landmarks in real-time even on hardware with limited processing power, such as mobile devices.

Object Detection with Pixel Intensity Comparisons Organized in Decision Trees

8 code implementations20 May 2013 Nenad Markuš, Miroslav Frljak, Igor S. Pandžić, Jörgen Ahlberg, Robert Forchheimer

We describe a method for visual object detection based on an ensemble of optimized decision trees organized in a cascade of rejectors.
