We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularly useful for the environmental assessment of landscapes. In our approach the 3D tree models are transformed to a quasi-3D tree database registering geometrical and shading information of tree surfaces, i.e. their normal vectors, relative depth, and shadowing of direct sunlight ...

In this study we intend to investigate the typical phenomena in shadowing speech and work out a tentative scheme for shadowing speech labeling. Our aim is two-fold: a) to give useful feedback to students and teachers who are using shadowing as a way of language learning; b) to explore the possibility of automatic assessment and error detection of shadowing speech. We firstly labeled a shadowing...

Let X be a compact metric space and f be a continuous map from X into itself. In this paper, we introduce the concept of the sequence asymptotic average shadowing property, which is a generalization of the asymptotic average shadowing property. In the sequel, we prove some properties of the sequence asymptotic average shadowing property and investigate the relationship between the sequence asym...

  In this paper, we present some important dynamical concepts on uniform space such as the minimal systems, shadowing, and strong shadowing. We explain definitions theorems definition expansive, weak generator, proof of for them. prove that if  be a homeomorphism compact  then  has shadowing only has so also show  and two homeomorphisms spaces ,  is conjugacy from ...

High-resolution satellite imagery (HRSI) offers great possibilities for urban mapping. Unfortunately, shadows cast by buildings in high-density urban environments obscure much of the information in the image leading to potentially corrupted classification results or blunders in interpretation. Although significant research has been carried out on the subject of shadowing in remote sensing, very...
