Abstract:
1. A method of representing an object appearing in an image or a sequence of images, by processing signals corresponding to the image, the method comprising deriving a plurality of pairs of co-ordinate values for peaks of the outline of the object in curvature scale space on the basis of the signals and applying a transformation to said co-ordinate values to arrive at a representation of the outline, wherein said transformation is in the form of y′=a pow (y,b)+c, where a, b and c are constants and pow (y,b) denotes y to the power b, where y represents one co-ordinate value of the pairs of co-ordinate values, and y′ represents said one co-ordinate value of the pairs of co-ordinate values after said transformation is applied.
