The visual appearance of real-world surfaces is the net result of surface reflectance
characteristics when exposed to illumination. Appearance models can be constructed using …

Many recent approaches to ball detection in robot soccer reduce the task to edge-based
circle detection, or training a classifier to detect specific balls with known colour or surface …

Phenomenological appearance models capture surface appearance through mathematical
modelling of the reflection process. Theoretically, the space of all possible images of a fixed …

Recognition of object classes in natural images has made tremendous progress in recent
years. Today's approaches often rely on powerful learning approaches as well as robust …

In recent years, impressive results have been reported for the recognition of individual object
classes, based on the combination of robust visual features with powerful statistical learning …
