1. A method for feature sensing on a sequence of image frames, comprising: a step for transforming each image frame using a wavelet transformation to generate a transformed image frame; a step for initializing node locations associated with wavelets jets of a model graph to the transformed image frame by moving the model graph across the transformed image frame and placing the model graph at a location in the transformed image frame of maximum jet similarity between the wavelet jets at the node locations and the transformed image frame; a step for tracking the location of one or more node locations of the model graph between image frames; and a step for reinitializing a tracked node if the node's position deviates beyond a predetermined position constraint between image frames.
