world production of caviar from the farmed sturgeon has recently so increased that in addition to compensate reduction of natural resources of sturgeon, it has also increased its share in the world market for caviar and its substitutes. although belarus, china and norway are currently considered as the main exporting countries of caviar and its substitutes but, iran solely exports caviar from s...

Engle and Manganelli (2004) propose CAViaR, a class of models suitable for estimating conditional quantiles in dynamic settings. Engle and Manganelli apply their approach to the estimation of Value at Risk, but this is only one of many possible applications. Here we extend CAViaR models to permit joint modeling of multiple quantiles, Multi-Quantile (MQ) CAViaR. We apply our new methods to estim...

BACKGROUND The international wildlife trade is a key threat to biodiversity. Temporal genetic marketplace monitoring can determine if wildlife trade regulation efforts such as the Convention on International Trade in Endangered Species (CITES) are succeeding. Protected under CITES effective 1997, sturgeons and paddlefishes, the producers of black caviar, are flagship CITES species. METHODOLOG...

In the proposed computer assisted visual interactive recognition (CAVIAR) methodology, a parameterized geometrical model serves as the human-computer communication channel. The iterative CAVIAR process is modelled as a finite state machine. A flower recognition system is implemented based on the proposed methodology. Evaluation on 30 subjects shows that 1) the accuracy of the CAVIAR system is 9...

Computer Assisted Visual Interactive Recognition, or CAVIAR, has proven to be an effective methodology for integrating human and machine expertise in addressing challenging pattern recognition tasks. In this paper, we examine the application of the CAVIAR paradigm to problems arising in real-time document analysis in the field. We identify hurdles we expect to encounter, propose potential solut...
