The Performance of Camera Translation Direction Estimators From Optical Flow: Analysis, Comparison, and Theoretical Limits

An error analysis of camera translation direction estimation from optical flow using linear constraints

A linear method using optical ow to recover the translation direction of a moving camera has been previously presented. This algorithm produced a biased estimate and various compensation techniques have been proposed. The results of an error analysis of the diierent approaches containing expressions for the expected mean vectors and covariance matrices of the translation estimates are presented...

Comparison between single and double flow plane solar heaters considering gas radiation effect

ABSTRACT: In this paper, the thermal characteristics of single and double flow plane solar heaters with radiating working gas were analyzed and compared by numerical analysis for the first time. The laminar mixed convection gas flow in the heaters was numerically simulated by the CFD method using the finite volume technique. The set of governing equations included the conservation of mass, mome...

Unbiased Estimation of Camera Translation Direction from Optical Flow Using Linear Constraints

Theoretical comparison analysis of long and short external cavity semiconductor laser

In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...
