Accuracy Of Depth Estimation Research Articles

Facts on optic flow

We employ an optimal solution to both the "shape from motion problem" and the related problem of the estimation of self-movement on a purely optical basis to deduce practical rules of thumb for the limits of the optic flow information content in the presence of perturbation of the motion parallax field. The results are illustrated and verified by means of a computer simulation. The results allow estimates of the accuracy of depth and egomotion estimates as a function of the accuracy of data sampling and the width of field of view, as well as estimates of the interaction between rotational and translational components of the movement.

Statistical evaluations of an automatic magnetic interpretation method for semi-infinite dykes

The performance of an automatic magnetic interpretation technique with regard to the accuracy of depth and width estimation has been studied using statistical techniques and theoretically generated anomalies over semi-infinite magnetized dykes. The automatic interpretation was based on the method of Koulomzine et al. Geophysics Vol. 35. This study revealed that the method produces generally reliable depth estimates over a wide range of geologically realistic models but the absolute accuracy of both depth and width estimates vary considerably and appear to be dependent on the actual depth-to-width ratio of the dyke. The automatic interpretation procedure was also found to provide more accurate estimates of depth and width when the original anomaly was asymmetrical as opposed to symmetrical.
