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...

This thesis deals with rational investors who maximize their expected utility in incomplete markets. In Part I, we consider models where incompleteness is induced by jumps and stochastic volatility. Using martingale methods we determine optimal investment strategies for power utility in a wide class of different models. Moreover, we show how first-order approximations of utility-based prices an...

Abstract Within the framework of banking efficiency analysis, we propose a methodology for computing unobservable shadow prices nonperforming loans ( NPL ). Our approach is to include as an undesirable output variable in distance function stochastic frontier analysis. We conduct panel study US and European banks during most recent financial crisis by adopting semi-nonparametric Fourier specific...

the light in modern concept has accompanied by theater as one of the formative elements of showing art from the first days of theater emergence and todays various functions have been defined for that and it has been and is being used for different purpose. on the other hand, the light is always with shadow on the scene and lack of light causes to darkness on the scene. so, the light, shadow, an...

Figure 1: Comparison between trapezoidal shadow maps (TSMs) and subdivided shadow maps. a) TSM with 1K×1K shadow map, b) TSM with 4K×4K shadow map, and c) 1K×1K subdivided shadow map. This configuration with a small angle between the light and view directions is difficult for prior methods. Even with the largest shadow map that can be allocated on current hardware, TSMs are not able to match th...

Shadow detection and removal in various real life scenarios including surveillance system, indoor outdoor scenes, and computer vision system remained a challenging task. Shadow in traffic surveillance system may misclassify the actual object, reducing the system performance. However, shadow causes problems in computer vision applications such as segmentation, object detection and object countin...
