- W2017478052 abstract "The optical flow computation has been widely studied motivated by a broad range of applications. We proposed a solution base on optical identity (OFI) using Correlation image sensor (CIS). If the frequency of the CIS' reference signals is ill-chosen, the SNR of the amplitude of the complex correlation image is small, and it is difficult to solve OFI stably. When we choose the frequency of the sinusoidal reference signals w satisfies wT=2n Pi the optical flow identity (OFI) holds, where n is an integer, T is the frame time of the CIS, and Pi is the circle ratio. We define G(w) satisfying wT=2nPi by the sum of the amplitude of the complex sinusoidally modulated image over all pixels, and maximize it to give a solution of the frequency-tuned problem." @default.
