This work presents a new method for automatic facial feature tracking in video sequences. In this method, a discrete face template is represented as a linear combination of continuous 2D odd-Gabor wavelet functions.The weights and 2D parameters (position, scale and orientation) of each wavelet are determined optimally so that the maximum of image information is preserved for a given number of w...

Runoff estimation resulted from precipitation is the basis of more study in various develop and exploit design from water resource, then its measure and calculation due to environmental bottlenecks, always have a plenty problem. As a result of the importance of output runoff estimation and flood volume in watershed for the sake of country integrated watershed management in this study tried to 9...

Reducing the product development cycle time is one of the most important and challenging problems faced by the industry today. As the functionality and complexity of devices increases, so does the time required to design, test, and develop the devices. Developing products rapidly in the face of this increasing complexity requires new methodologies and tools. This paper presents a methodology fo...

The ability to estimate resource consumption of SQL queries is crucial for a number of tasks in a database system such as admission control, query scheduling and costing during query optimization. Recent work has explored the use of statistical techniques for resource estimation in place of the manually constructed cost models used in query optimization. Such techniques, which require as traini...

Estimating the cardinality (i.e., the number of answers) of conjunctive queries is particularly difficult in RDF systems: queries over RDF data are navigational and thus tend to involve many joins. We present a new, principled cardinality estimation technique based on graph summarisation. We interpret a summary of an RDF graph using a possible world semantics and formalise the estimation proble...

The Mineral Potential Project currently being undertaken in British Columbia requires estimation d unknown mineral resources. The method of resource assessment known as the BC Mineral Resource Assessment Process [19931. is described by Kilby (1995, this volume) and in Grunsky et al. (1.994). The method is based on the three-part ssessment methodology developed by the United States Geologica...

This paper summarizes major achievements and challenges of software resource estimation over the last forty years. We address critical issues that enabled major achievements such as the development of good model forms, criteria for evaluating models, methods for integrating expert judgment and statistical data analysis, and processes for developing new models that cover new software development...
