This paper presents a new efficient algorithm for fitting an ellipse to scattered points. By minimizing the algebraic distance subject to the constraint of length of semi-minor axis, the new approach incorporates the ellipticity constraint into the normalization factor. The proposed method guarantees an ellipse-specific solution even for the noised data spaning a small section of the elliptic arc...
Ballistic Trajectory Computation Program is a part of weapon delivery system and it is responsible for accurate delivery of the weapon. Mach number (M) and Coefficient of drag (Cd) are critical parameters in external Ballistic computation and are used in computation of Impact Point. Cd Vs M relation is not available in a functional form. These data are available in discrete form from Wind Tunnel....
High precision three-dimensional reconstruction and measurement of industrial objects by digital imagery is one of the most active research fields in Computer Vision and Digital Photogrammetry. Due to most of industrial sheet-metal parts are made up of linear features, it is important to extract lines from 2D images accurately. Meanwhile, quality of lines will further to decides on precision of reconstruction...
