    Simple gestalt algebra

    The laws of Gestalt perception rule how parts are assembled into a perceived aggregate. This contribution defines them in an algebraic setting. Operations are defined for mirror symmetry, repetition in rows, a...

    On the semantics of object-oriented landmark recognition

    Computer vision is an ever more important means for the navigation of UAVs. Here we propose a landmark recognition system looking for salient man-made infrastructure. An object-oriented structural system is pr...

    Building extraction based on stereo analysis of high-resolution SAR images taken from orthogonal aspect directions

    In this paper high-resolution SAR images of an urban scene are analyzed in order to infer buildings and their heights from the different layover effects in perpendicular taken views. Due to the strong dependen...

    Where Is the Hole Punch? Object Localization Capabilities on a Specific Bureau Task

    In this paper, knowledge-based recognition of objects in a bureau scene is studied and compared using two different systems on a common data set: In the first system active scene exploration is based on semant...
