| Abstract: | The object tracking is a problem which is very often addressed by various approaches as the background subtraction, visual constancy or geometric flow, to cite only a few.The contribution of this paper is twofold: First, it proposes an enhanced feature-weighted gradient, enhancing the contours of the object characterized by this feature, and attenuating the gradient amplitude wherever the feature is not found.The second, and main contribution, is a new integrator for active-contours based tracking. It uses the gradient alongside the object contours and generates a bidirectional attraction field.The combination of the contour tracking and the weighted gradient is illustrated on the driver's-face tracking problem, where the illumination conditions (brightness, colour) change as the vehicle passes through different environments. | ||
