High dynamic range of illumination may cause serious distortions and other problems in viewing and further processing of digital images. In this paper a new tone reproduction preprocessing algorithm is introduced which may help in developing hardly or non-viewable features and content of the images. The method is based on the synthetization of multiple(More)
Recently, the importance of information enhancement methods in digital image processing has increased significantly. A large amount of research has been focused on information retrieval and image understanding. Typical examples are searching for similar objects/images in large databases and understanding the objects in images. The main point of these tasks(More)
High dynamic range of illumination may cause serious distortions and information loss in the viewing and further processing of digital images. On the other hand, digital processing can often improve the visual quality of real-world photographs or views. Recently, HDR imaging techniques have come into the focus of research because of their high theoretical(More)
The shape of the objects is an important property, which can be used by many applications. There are simple shapes, which can be acquired by the most of the 3D measurement devices. There are very complex surfaces, as well, which acquisition can be performed only by a small subset of the recently used techniques. The goal of our work is to develop a(More)
Recently, the number of different kind of 3D scanning devices and surface reconstruction algorithms has been growing rapidly. 3D Models can be used in a large range of exciting applications areas. For instance the industrial design, manufacturing, the held of medicine can be mentioned. In this paper an improved vision based 3D measurement system is(More)
