The imaging technology basing on binocular stereo vision of linear array camera can effectively detect foreign bodies existing in automobile chassis so that ensure the safety of people. However, the distortion of camera lens can influence the precision of system measurement and three-dimensional reconstruction. Because of the difference between the imaging principle of linear array camera and t...

There are two types of distortion of the loudspeaker system, the linear and the nonlinear distortions. We have tried to eliminate the linear distortion by digital filters. However, the more quantity of the elimination of the linear distortion, results in the more quantity of the nonlinear distortion. Therefore in order to make a high quality audio system we need to eliminate both the linear and...

Introduction: General health is composed of features that act as a shield in the face of stressful life situations and help couples have better performance in these situations. The present study was conducted to determine the role of cognitive belief, fusion and distortion in predicting the general health of couples. Materials and Methods: Research method was descriptive method. Populatio...

BACKGROUND In this paper, we propose a non-linear calibration method for hand-eye system equipped with a camera undergoing radial distortion as the rigid endoscope. Whereas classic methods propose either a separated estimation of the camera intrinsics and the hand-eye transform or a mixed non-linear estimation of both hand-eye and camera intrinsics assuming a pin-hole model, the proposed approa...

A Distortion Contribution Analysis (DCA) obtains the distortion at the output of an analog electronic circuit as a sum of distortion contributions of its sub-circuits. Similar to a noise analysis, a DCA helps a designer to pinpoint the actual source of the distortion. Classically, the DCA uses the Volterra theory to model the circuit and its sub-circuits. This DCA has been proven useful for sma...

This paper describes several consequences of a linear–nonlinear interaction that was recently found to be of importance in microwave circuits that produce passive intermodulation (PIM) distortion. This paper briefly discusses how this linear–nonlinear interaction operates in an example system. It then discusses how an understanding of the linear–nonlinear interaction allows us to distinguish be...
