<p>A method of recognising and detecting colours is disclosed, to allow recognition and sorting of objects. Pixels of a colour image of an object to be recognised are received, the hue, intensity and/or saturation of each pixel is determined, the hue, intensity and/or saturation of each received pixel is allocated to a plurality of predetermined hue, intensity and/or saturation bands respectively to obtain hue, intensity and/or saturation distribution values respectively for the colour image, and the distribution values for the colour image are compared with the distribution values from one or more reference objects to determine if the object is recognised as a said reference object. This method of object recognition is independent of the image complexity and the number of colours on the object to be recognised. The method operates to compare a hue signature of the object to be recognised with a hue signature of a reference object.</p> |
