Detectability of Optical Flow by Temporal Spatial Gradient Method and an Algorithm for 3-D Motion Estimation
Transactions of the Society of Instrument and Control Engineers
Conventional methods of detecting the 3-D motion of an object from the sequence of brightness patterns in image frames used to be composed of two steps; first computing the optical flow from the brightness patterns, and then detecting the 3-D motion by interpreting the optical flow. The detectable magnitude of optical flow is dependent on pixel sizes, sampling periods, and spatial frequencies contained in the brightness patterns. However, any quantitative relations among them have yet beendoi:10.9746/sicetr1965.24.76 fatcat:bwl2c2y5rza7fnoesvsmcgkt3a
