| Abstract(in English) | In this paper is discussed the use of both an conventional intensity image and a complex-valued correlation image to retrieve the optical flow. The correlation image consists of the correlation integrals between a chosen electrical signal and the time-varying light intensity, which can be acquired throught the use of the correlation image sensor (IEEE Trans. ED-50, 10, 2059-2066, 2003). This novel approach is examined and compared with traditional methods in several aspects : 1) image properties for various patterns and velocity, 2) detectability and accuracy vs. velocity, and 3) complex correlation image response to motion singularities. The comparison is made with both some standard image sequences extended for the modulated imaging, correlation image simulation using a raytracer. |
