Matching mixtures of curves for human action recognition
Elsevier
M. Vrigkas, V. Karavasilis, C. Nikou and I. A. Kakadiaris, Matching mixtures of curves for human action recognition, Computer Vision and Image Understanding, Vol. 119C, pp. 27-40, February 2014.
A learning-based framework for action representation and recognition relying on the description of an action by time series of optical flow motion features is presented. In the learning step, the motion curves representing each action are clustered using Gaussian mixture modeling (GMM). In the recognition step, t
A novel framework for motion segmentation and tracking by clustering incomplete trajectories
Elsevier
V. Karavasilis, K. Blekas and C. Nikou. A novel framework for motion segmentation and tracking by clustering incomplete trajectories. Computer Vision and Image Understanding, Vol. 116, No 11, pp. 1135-1148, 2012.
In this paper, we present a framework for visual object tracking based on clustering trajectories of image key points extracted from an image sequence. The main contribution of our method is that the trajectories are automatically extracted from the image sequence and they are provided directly
Visual tracking using the earth mover's distance between Gaussian mixtures and Kalman filtering
Elsevier
V. Karavasilis, C. Nikou and A. Likas. Visual tracking using the earth mover's distance between Gaussian mixtures and Kalman filtering. Image and Vision Computing, Vol. 29, No 5, pp. 295-305, 2011.
In this paper, we demonstrate how the differential Earth Mover's Distance (EMD) may be used for visual tracking in synergy with Gaussian mixtures models (GMM). According to our model, motion between adjacent frames results in variations of the mixing proportions of the Gaussian components representing the ob
