We generalize here the use of the 1D Boolean model for the analysis of grey level textures. Each grey image is first split into eight binary images using different criteria. Each of these binary images is separately analysed with the help of the 1D Boolean model and features are extracted from it. The final grey texture recognition is performed on the basis of these features using several class...

Rendering haptic textures seamlessly out of triangle meshes just by using geometry requires heavy work and does not allow high sampling rates for detailed, rugged models. Better approaches simulate surface texture without increasing much the complexity or processing cost, at the expense of fidelity of perception. We propose a method for rendering local height field maps out of an underlying tri...

With the advent of image based modeling techniques, it becomes easier to apply textures extracted from reality onto virtual worlds. Many repetitive patterns (structural textures) in human constructions can be parametrized with procedural textures. These textures offer a powerful alternative to traditional color textures, but they require the artist to program the desired effects. We present a s...

In the following paper, a new method for fast and accurate volume intensity and color integration is elaborated, which employs wavelet decompositions and texture mapping. At this point, it comprises and unifies the advantages of recently introduced Fourier domain volume rendering techniques and wavelet based volume rendering. Specifically, the method computes analytic solutions of the ray inten...

Regions of visual texture can be automatically segregated from one another when they abut but also discriminated from one another if they are separated in space or time. A difference in mean orientation between two textures serves to facilitate their segmentation, whereas a difference in orientation variance does not. The present study further supports this notion, by replicating the findings o...

Thermal infrared (TIR) images of the building hull are often used for detecting damaged and weak spots in the insulation of the building hull. However, imaging and manually analysing each face is very time consuming. This process can be carried out more efficiently using a mobile mapping system (MMS) equipped with a TIR video camera. Frontal façades of the buildings which are visible from stree...
