Patent ID: 7155033

Claim:
A method of coarse representation of a shape of a visible object in a digital picture comprising the steps of: segmenting visible objects from the digital picture: extracting a bitmap for an object of interest from the segmented visible objects; and estimating from the bitmap a display aspect ratio and a binding box for the object of interest, wherein said estimation step additional comprises estimating in pixel units a set of parameters for the binding box; and normalizing the pixel units to form a feature vector representing the binding box; searching a video database having visible objects, each visible object having an associated feature vector, as to find those objects whose feature vectors match the feature vector of the object of interest; wherein said searching step additionally comprises computing aspect ratios for all visible objects in the video database; computing distances according to a specified distance metric between the desired aspect ratio and the aspect ratios for the visible objects in the video database; sorting the distances in descending order to produce a sort list of aspect ratios and associated visible objects; and displaying the visible objects associated with the aspect ratios that are at the top of the sort list.
