Patent ID: 7738690

Claim:
A verification method for determining areas within an image corresponding to monetary banknotes, the method comprising: dividing the image into a plurality of image sections; generating a banknote boundary map having border sections selected from the image sections, the border sections corresponding to a boundary of monetary banknotes within the image; generating a texture decision map having texture sections selected from the image sections, the texture sections having a texture value within a valid range according to a valid monetary banknote; determining a number of objects in the texture decision map by removing texture sections in the texture decision map that correspond to the border sections in the banknote boundary map; calculating a texture property value for each object according to a texture feature map having a texture feature value for each image section; calculating a shape property value for each object; and further removing texture sections from the texture decision map corresponding to objects that do not have the texture property value within a first predetermined range and the shape property value within a second predetermined range.
