— We report an autonomous observation system with multiple pan-tilt-zoom (PTZ) cameras assisted by a fixed wideangle camera. The wide-angle camera provides large but low resolut...
In this work we describe a set of visual routines, which support a novel sensor free interface between a human and virtual objects. The visual routines detect, track and interpret ...
Software decay is a phenomenon that plagues aging software systems. While in recent years, there has been significant progress in the area of automatic detection of “code smells...
Although quality is not easy to evaluate since it is a complex concept compound by different aspects, several properties that make a good object-oriented design have been recogniz...
As an object-oriented system evolves, its architecture tends to drift away from the original design. Knowledge of how the system has changed at coarse-grained levels is key to und...
