Abstract

It is of crucial interest for computer controlled camera systems to exhibit what is possessed by Human Vision System (HVS), which demonstrates high efficiency and effectiveness in carrying out routine perceptive tasks. To that end a wealth of different variable resolution methods have been developed to emulate the unique structure of the HVS in the research discipline of active vision. In our previous work we have developed the Foveate Wavelet Transform (FWT) as a new variable resolution representation with the benefits such as close emulation of the HVS, data reduction, and linearity preservance. Scan path is employed by the HVS to observe a scene which is larger than its field of view. An intelligent scanning scheme is developed in this paper in an effort to emulate the scan path of the HVS by taking advantage of the unique feature of the FWT. With this new scanning scheme, an ad hoc strategy is adopted to determine the next fixation point based on both a prescribed scanning order and the instant interest of the point due to its spatial and temporal properties. Preliminary experiments post encouraging performance of this proposed scanning scheme.
