the RoboCup competition has brought back to attention the classification of objects in a controlled illumination environment. We present a very fast classifier to achieve image segmentation. Our methods are based on the machine literature, but adapted to robots equipped with low cost image-capture equipment. We then present new fast methods for object recognition, based on also rapid methods for blob formation. We describe how to extract the skeleton of a polygon and we use this for object recognition.

the development of an on line computer based classification system for the real time classification of different composites is addressed in this study. Different parameters were collected simultaneously when embedded sensors (dielectric, optical fibre, and piezoelectric sensors) were used within two different composite matrices during the curing process. the measurements were used by an algorithm-based software as a logged data file, resulting in to induction of a decision tree. Later, a systematic software is designed based on the rules derived from this decision tree, to recognise the type of composites used in the experiment together withrecognition of their physical and mechanical characteristics. this is a new approach to data acquisition in intelligent materials produced by smart manufacturing system.

We present a novel approach to pose and illumination invariant face recognitionthat combines two recent advances in the computer vision field: component-based recognition and 3D morphable models. First, a 3D morphable model is used to generate 3D face models from three input images from each person in the training database. the 3D models are rendered under varying pose and illumination conditions to build a large set of synthetic images. these images axe then used to train a component-based face recognition system. the resulting system achieved 90% accuracy on a database of 1200 real images of six people and significantly outperformed a comparable global face recognition system. the results show the potential of the combination of morphable models and component-based recognition towards pose and illumination invariant face recognition based on only three training images of each subject.
