Image frames are stored as a plurality of pixel values. An image frame is viewed in which a perceived object (301) is to be distinguished from the remainder of the image frame. Input signals identify control positions in proximity to the boundary of said object. Pixel values are compared around each of the control positions to define a local colour transition. Colour transitions for the whole obje...
