Rendering translucent materials in real time is usually done by using surface diffusion and/or (translucent) shadow maps. The downsides of these approaches are, that surface diffusion cannot handle translucency effects that show up when rendering thin objects, and that translucent shadow maps are only available for point light sources. Furthermore, translucent shadow maps introduce limitations ...

Shadow detection in real scene images is always a challenging but yet interesting area. Most shadow detection and segmentation methods are based on image analysis. This paper aimed to give a comprehensive and critical study of current shadow detection methods. Various approaches have been discussed related to shadow detection in images. The principles of these methods rely on intensity differen...

in a fictional movie, shadow is not only a technical and thematic concept, but also one of the most illustrative and expressing aesthetic elements of the movie. shadows vast dimensions have led to various discussions and studies along the history of cinema. the main theory of this essay is that a shadow is a comprehensible phenomenon whose interpretation and understanding are greatly essential ...

Since the energy consumption has become one of the crisis of modern buildings, modeling the Iranian past architecture patterns could be helpful. The shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. However, using passive techniques, the Iranian traditional bazaars architecture solved the problems regard...

Image may contain shadow, which can lead to serious problem for full exploitation of image. This paper proposes A Novel Processing Chain to solve this problem. The main aim of this chain process is not only detect shadow region form image but also remove shadow region and reconstruct shadow less image. In this chain process, initially we classified shadow vs. nonshadow region by using binary cl...

We present a system for interactive shadow editing from single images which includes the manipulations of shape, distribution, sharpness and darkness of shadows according to the features of existing shadows. We first obtain a shadow-free image, shadow boundary and its registered sparse shadow scales using an existing shadow removal method. The modifiable features of the shadow are synthesised f...

In remote sensing images, shadows created by big tower, bridges, tree. It may destroy the information of an image. Missing information has a direct effect on common analysis and processing of image, this leads to inefficient classification. To separate shadow and non shadow regions, morphological feature is consider for segmentation. Relevance Vector Machine (RVM) classifier can also classify b...
