This paper proposes an approach for a robust tracking method to the objects intersection with appearances similar to a target object. The target is image sequences taken by a moving camera in this paper. Tracking methods using color information tend to track mistakenly a background region or an...

This paper proposes a new approach to recover the polyp shape from an endoscope image using a photometric constraint equation considering two light sources. The procedures are as follows. First, obtain the initial depth distributions by optimizing photometric equation obtained from two light...

This study investigates the dependence structure of returns of different types of equity REIT. Copulas, which provide a tractable way of modelling non-linear dependency among random variables, are employed under financial time series framework. The model consists of two parts: the marginal part,...

Grounded in agency theory, this paper investigates the effect of board independence on managerial ownership. We exploit the passage of the Sarbanes-Oxley Act and the associated exchange listing requirements as an exogenous regulatory shock that raises board independence. Our...
