Technologies and applications for computer graphics

This paper presents some results of actual R&D related to imaging. This covers generation of images from abstract models as well as the analysis of images and the generation of models from images. First we introduce two applications for imaging in the medical area - MIS-Browser and 2D-Gel Electrophoresis. The focus of these applications are technologies for the management of very large image data e.g. originating from confocal raster microscopy and the extraction of features from images. In eNoteHistory image analysis is used for the identification of writers of music scores. From scanned handwritten music scores features are extracted that enable the identification of the writer of that music score. The technologies developed in ERSO go one step ahead. Based on extracted features of multiple images of an object or a scene and the matching of theses features between the images a 3D model is created. This model can be used in VR or AR presentations. The Virtual Showcase, the last example, is such an application for the presentation of augmented real objects. Here we use imaging for optical user tracking to control of the viewing process for the correct presentation of virtual objects in a virtual or real environment. Virtual objects are rendered from models and can create a virtual environment (VR) or augment a real environment (AR)
