Abstract:
A method and an apparatus localize an object part location in a digital image. The method according to one embodiment accesses digital image data containing an object part; obtains an initial position estimate for object part location of the object part; extracts a sub-image window around the initial position estimate of the object part location; calculates feature values based on pixel values within the sub-image window; and determines an updated position estimate for the object part location based on the calculated feature values.
