Shadow detection is useful in many applications like image segmentation, scene interpretation and object recognition/tracking. Shadow in images is formed when direct light from a light source cannot reach due to obstruction by an object. Shadow removal is a critical step for improving object detection and tracking. Many algorithms for shadow detection have been proposed in the literature. This ...

    Dynamic model,   regional economy,   innovation.   This paper presents a normative balance mathematical model of regional economy that contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. A method for estimation of the model parameters by application of parallel computations on multi-processors systems is presented. It is determined the...

The purpose of this paper is to try to analyze the Shadow Economy (SE) and its determinants by means of the Structural Equation Model (SEM)-Partial Least Squares (PLS). The overall topic of the SEM-PLS approach is controversially debated in the literature. In the past decades, the focus on the SE has increased and the range in the estimated size of this phenomenon is very divergent. By examinin...
