6. The method of claim 5 , wherein a third matrix of pixels is placed on the selected image feature at {center x−dx, center y−dy} coordinates and having a spatial extent determined from the sx and the sy scale factors to determine a third N-dimension descriptor, a third N-dimension signature, and a third traversal has signature to be stored in the media database.
5. The method of claim 1 further comprising: generating a second N-dimension descriptor for the selected image feature, the second N-dimension descriptor is determined from a second matrix of pixels placed on the selected image feature at {center x+dx, center y+dy} coordinates and having a spatial extent determined from the sx and the sy scale factors, wherein the second N-dimension descriptor comprises N digit values arranged in H groups of D dimensions; applying the first threshold to the second N-dimension descriptor to generate a second N-dimension signature having N binary values; generating a second combined descriptor based on the second N-dimension descriptor by combining the digit values in each group of D dimensions of the second N-dimension descriptor to create a combined digit value for each group, wherein each second combined descriptor comprises H=N/D combined digit values; and applying the second threshold to each combined digit value of the second combined descriptor to generate a second traversal hash signature having H binary values, wherein the second traversal hash signature, associated second N-dimension signature, associated second N-dimension descriptor, and associated {center x+dx, center y+dy, sx, sy}values are stored in a media database.
