1. A method for tracking an image of an object in a plurality of video frames, comprising: a processor determining in a first video frame in the plurality of video frames a set of discrete texture traces to a target location in a patch in the object in the first video frame to establish a reference model, the patch being generated by the set of discrete texture traces that connect to the target location from locations in a finite support region defined by a discrete trace length of a predetermined length n and a neighborhood relation scale and each discrete texture trace is a finite sequence of n quantized descriptions, wherein each quantized description includes a quantized description of a first location in the finite support region and a quantized description of a relation between the first location and a second location in the finite support region; and the processor detecting the target location in a second video frame by maximizing a score based on the reference model.
