A method of defining a location of a given object in an image of interest where the object is characterized by having a specified pattern and an additional property. The method includes: specifying portions of the image (102), identifying among the specified image portions a candidate image portion (104) comprising a portion of the specified pattern; defining an image region around the candidate image portion (106), the image region being composed of image portions, each comprising a portion of the specified pattern, the image region being surrounded by image portions not comprising a portion of the specified pattern; comparing the other property of the given object with same property at the identified region, and if the image region has the additional property of the given object (108), identifying the location of the given object as the location of the defined image region (110). The specified pattern may be smooth (ie no pattern.) The additional property may be colour or contour shape. |
