A method to determine range from a translationally blurred and a sharp image is presented. To decode the length of blur in the translationally blurred image, three decoding methods; minimization approach, Fourier transform approach, and method-of-slopes, were tested on various images. The results were found to be favorable for the minimization approach and the method-of-slopes. Ringing was encountered with the Fourier transform approach. The minimization approach is iterative and slow. The method-of-slopes was investigated further for the case of inclined plane surfaces and the results were found to be favorable. The method-of slopes can also determine disparity for cylindrical surfaces. A rotating mirror system is described, which simulates camera translation in order to produce a linearly blurred image, in real-time.en-USAll UHM dissertations and theses are protected by copyright.
