The Extended Hough Transform and its Applications in Active Vision Field
扩展Hough变换及其在主动视觉中的应用

In this paper, the extended Hough transform (EHT) is investigated. It is shown that it is impossible to give the necessary conditions of being an EHT. Two sufficient conditions, however, are introduced. In addition, the EHT is used to simulate a human vision system for the study of gaze control, a problem actively pursued in the active vision field currently.
