Bound and Conquer: Improving Triangulation by Enforcing Consistency

no code implementations27 Apr 2018 Adam Scholefield, Alireza Ghasemi, Martin Vetterli

We study the accuracy of triangulation in multi-camera systems with respect to the number of cameras.

SHAPE: Linear-Time Camera Pose Estimation With Quadratic Error-Decay

no code implementations24 Feb 2016 Alireza Ghasemi, Adam Scholefield, Martin Vetterli

We propose a novel camera pose estimation or perspective-n-point (PnP) algorithm, based on the idea of consistency regions and half-space intersections.

Pose Estimation

A Bayesian Approach to the Data Description Problem

no code implementations24 Feb 2016 Alireza Ghasemi, Hamid R. Rabiee, Mohammad T. Manzuri, M. H. Rohban

The proposed approach uses a Bayesian framework to precisely compute the class boundary and therefore can utilize domain information in form of prior knowledge in the framework.

Active Learning from Positive and Unlabeled Data

1 code implementation24 Feb 2016 Alireza Ghasemi, Hamid R. Rabiee, Mohsen Fadaee, Mohammad T. Manzuri, Mohammad H. Rohban

Such problems arise in many real-world situations and are known as the problem of learning from positive and unlabeled data.
