....motion on depth uncertainty and reinforces the need for modeling the uncertainty in computed depth. 3.1. Equations of Motion If the inter frame camera motion is sufficiently small, the resulting optical flow can be expressed to a good approximation in terms of the instantaneous camera velocity [6, 13, 33]. We will specify this in terms of a translational velocity T and an angular velocity R. In the camera coordinate frame (figure 2) the motion of a 3D point P is described by the equation dP T RxP dt Expanding this into components yields dX dt = RyZ R,Y dY dt = R:X RZ [1] dZ dt = ....

.... dX dt = RyZ R,Y dY dt = R:X RZ [1] dZ dt = T RxY R, X Now, projecting (X, Y, Z) onto an ideal, unit focal length image, X Y x yZ taking the derivatives of (x, y) with respect to time, and substituting in from equation (1) leads to the familiar equations of optical flow [33]: Ay Z 0 1 I21 (1 y2) xy x These equations relate the depth Z of the point to the camera motion T,R and the induced image displace ments or optical flow [Ax Ay] r. We will use these equations to measure depth, given the camera motion and optical flow, and to predict the change in the ....

.... shading with contour, Grimson s [6] use of shading in determining the surface orientation of feature point contours obtained from stereo, Aloimonos s methods [1] for combining shading and motion, texture and motion, and motion and contour, and Waxman s approach for combining stereo and motion [17]. The objective of this research is to work on the integration of shape from X modules. In particular, we are interested in combining the depth information (3 D shape) from two very important cues, stereo and shading. Shape from shading is the estimation of 3 D shape from a 2 D image given the ....
