In an automated feature-based motion analysis of multiple frames, correspondence da ta are usually noisy and fragmented. We developed a technique that gradually refines the initial noisy correspondence d a t a and links fragments of a single trajectory using feedback from 3-0 motion estimation. First, 3-0 motion parameters are estimated using the initial correspondence data. Then, each noisy tr...

In this paper we propose a confidence measure for block-based motion vector field. The measure is calculated as an average of two a posteriori estimates which reflect various aspects of MVF accuracy: motion-compensated interframe difference distribution and motion vectors distribution. Experimental results show that the proposed measure outperforms its contemporary counterpart while demanding l...

Human motion retrieval and analysis is a useful means of activity recognition to 3D human bodies. An efficient method proposed estimate by using symmetric joint points limb features various parts based on regression task. We primarily obtain the coordinates located waist hip points. By introducing three critical feature torso points’ matching video sequences, its asymmetric will not be affected...

Skid‐steered mobile robots have been widely used in exploring unknown environments and in military applications. In this paper, the tuning fuzzy Vector Field Orientation (FVFO) feedback control method is proposed for a four track wheel skid‐steered mobile robot (4‐TW SSMR) using flexible fuzzy logic control (FLC). The extended Kalman filter is utilized to e...

This paper describes a new method for creating visually realistic moving facial image sequences that retain an actor's personality (individuality, expression and characteristic movements) while altering the facial appearance along a certain specified facial dimension. We combine two existing technologies, facial feature tracking and facial image transformation, to create the sequences. Examples...
