Most computer vision algorithms have parameters that must be hand-selected using expert knowledge. These parameters hinder the use of large computer vision systems in real-world applications. In this work, a method is presented for automatically and continuously tuning the parameters of algorithms in a real-time modular vision system. In the training phase, a human expert teaches the system how to adapt the algorithm parameters based on training data. During operation, the system measures features from the inputs and outputs of each module and decides how to modify the parameters. Rather than learning good parameter values in absolute terms,
incremental
changes are modelled based on relationships between algorithm inputs and outputs. These increments are continuously applied online so that parameters stabilise to suitable values. The method is demonstrated on a three-module people-tracking system for video surveillance.
