Motion-distorted composite-frame restoration

Applied Optics, 1999
Many imaging systems produce pictures by the superimposition of two fields of frames of interlaced sequences. Pictures obtained in this way, which are termed composite frames, are severely degraded if relative motion between the camera and the scene occurs.

Motion Interpolation With G2 Composite Bézier Motions

20th Design Automation Conference: Volume 1 — Dynamic Mechanical Systems; Geometric Modeling and Features; Concurrent Engineering, 1994
Abstract This paper deals with smooth motion interpolation. Recently, a direct construction algorithm was developed for designing piecewise parametric motions with second order geometric continuity (G2). The present paper provides a refined version of the G2 spline algorithm and shows how the G2 spline motion can be used to fulfill the ...

Motion Compensated Composite Color Coding

IEEE Transactions on Communications, 1983
This paper is concerned with motion compensation techniques for predictive coding of the composite (frequency multiplexed) color television signal. Motion estimation algorithms developed in this paper are recursive and are extensions of our previous algorithms developed for baseband luminance signals. We show, by computer simulations, that displacement
