The proposed method consists of three stages. First, we apply a hierarchical block-based technique to detect and eliminate the moving regions from the background, and meantime we estimate the initial guess of the global motion. Next, we employ a hierarchical feature-based technique on the retained background regions to refine and derive the precise global motion. Last, we refine the segmentatio...

In this work an automatic method to discover multiple sclerosis (MS) lesions is presented. The technique makes use of an original implementation of the watershed based hierarchical segmentation algorithm applied to Magnetic Resonance (MR) images of the brain. The hierarchical approach is needed because of its merging phase where lesions are isolated from the over-segmented image produced by wat...

The paper addresses the following problems: (1) a brief survey on wireless mobile communication technologies including evolution, history evolution (e.g., chain of system generations 0G, 1G, 2G, 3G, 4G, 5G, 6G, 7G); (2) using a hierarchical structural modular approach to the generations of the wireless communication systems (i.e., hierarchical combinatorial modeling of the communication technol...

Evolution means different things at different stages of development. Higher stage explanations for it are downward assimilated at lower stages. Different scientific explanations for evolution also reflect different stages of development. Hierarchical complexity of tasks in evolution is a behavioral analytic explanation. It is selection processes of various kinds in tandem with changes in select...

This paper addresses the problem of learning control skills from observation. In particular, we show how to infer a hierarchical, reactive program that reproduces and explains the observed actions of other agents, specifically the elements that are shared across multiple individuals. We infer these programs using a three-stage process that learns flat unordered rules, combines these rules into ...

the purpose of this study was to investigate the moderating role of conscientiousness personality trait in the relationship of emotional exhaustion with job performance (task performance, organizational citizenship behaviors). the participants of this study consisted of 400 high school teachers in khuzestan province (260 male & 140 female) that were selected by multi-stage random sampling metho...

social responsibility is a collection of duties and commitments the organization should undertake to preserve, treat and help the society in which it operates. the aim of this study was to investigate the effect of experience mediator on the relationship between managers' social responsibility and customer loyalty in sport clubs. the research method was correlation- survey. the statistical...
