....gradually. Naturally, when class appearance varies, the most discriminating set of features also varies. The issue of on line feature selection has rarely been addressed in the literature, especially under the hard constraint of speed required for target tracking. The nearest relevant work is [11], which dynamically switches between five color spaces to improve face tracking performance. Section 2 presents a brief look at off line discriminative feature selection in the field of pattern classification. Section 3 adapts these ideas to the task of target tracking. Since the goal is to ....

....approaches assume much narrower and incomplete models of the gesticulating person. Feature based approaches assume that the users gesture movements give rise to image features that can be detected and used for tracking. Common visual features used are contours [61 63, 45] points [64 67] color [68, 69] and motion [70] Finally image content itself can directly serve as image features [71 74] Contour based approaches suffer from the requirement that they usually require some form of more detailed model of the target to be tracked. This makes the approaches often unsuitable because the inherent ....
