TL;DR
It is shown here that by using either the temporal or the spatial derivatives of the retinal flow, linear equations in the motion parameters can be derived, which can then be used to compute themotion parameters uniquely.
Abstract
The perception of rigid motion from the optical flow generated on the retina is considered. In general, the problem does not have a unique answer. In addition, the equation that constrains the motion parameters based on flow information is nonlinear. We show here that by using either the temporal or the spatial derivatives of the retinal flow, linear equations in the motion parameters can be derived, which can then be used to compute the motion parameters uniquely.

An iterative implementation is shown which successfully computes the optical flow for a number of synthetic image sequences and is robust in that it can handle image sequences that are quantized rather coarsely in space and time.

It is shown that from a monocular view of a rigid, textured, curved surface it is possible, in principle, to determine the gradient of the surface at any point, and the motion of the eye relative to it, from the velocity field of the changing retinal image, and its first and second spatial derivatives.

A model of how humans sense the velocity of moving images, using a set of spatial-frequency-tuned, direction-selective linear sensors, agrees qualitatively with human perception.

A local approach by minimization of the squared differences between a second-order Taylor expansion of gray values from one frame and the observed gray values within the same window from the next frame appears to be an interesting model for the local computation of optical flow.

A theoretical analysis of the conditions under which this computation of an instantaneous two-dimensional velocity field yields the correct velocity field suggests that the solution is physically plausible; empirical studies show the results to be consistent with human motion perception.

It is argued that in the stationary world, an observer can in principle compute the parameters of his egomotion, and following this, the relative depth map of the stationary environment solely from the instantaneous positional velocity fields (IPVF).

It is found that optical flows cannot directly specify egomotion or relative motion of objects with respect to the observer, and that the relative depth and local surface orientation is unambiguously contained in optical flows.

This analysis is based on shape-from-motion proposition, which states, that given the first spatial derivatives of the orthographically projected velocity and acceleration fields of a rigidly rotating regular surface, then the angular velocity and the surface normal at each visible point on that surface are uniquely determined up to a reflection.
