This paper details the results of a Face Authentication Test (FAT2004) [2] held in conjunction with the 17th International Conference on Pattern Recognition. The contest was held on the publicly available BANCA database [1] according to a defined protocol [7]. The competition also had a sequestered part in which institutions had to submit their algorithms(More)
This paper describes the extension of an existing commercial lane detection system for marked roads by the detection and classification of soft shoulders, curbs and guardrails. Available sensors are a front directed gray scale camera and the CAN-bus data. To accomplish our goals we use two complementing methods. The first method is meant for localizing the(More)
Face recognition systems have to deal with the problem that not all variations of all persons can be enrolled. Rather, the variations of most persons must be modeled. Explicit modeling of different poses is awkward and time consuming. Here, we present a subsystem that builds a model of pose variation by keeping a model database of persons in both poses,(More)
Built on the principles of “Learning from Nature” and “Self-organization” Elastic Bunch Graph Matching for face recognition is a defining example for Organic Computing methodology. Here, we follow these principles further to advance the method in two respects. First, the requirement for manual annotation of landmarks is reduced to one single face, from(More)
Image time series of high temporal and spatial resolution capture land surface dynamics of heterogeneous landscapes. We applied the ESTARFM (Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model) algorithm to multi-spectral images covering two semi-arid heterogeneous rangeland study sites located in South Africa. MODIS 250 m resolution and(More)
We present our idea of solving parts of the vision task with an organic computing approach. We have designed a multiagent system (MAS) of many different modules working on different tasks towards the same goal, the recognition of a human gesture. We will introduce our point of view of an agent and how a group of agents can cooperate with other organically(More)
