A theory for detecting general curve families by means of symmetry measurements is presented. Symmetries are modeled by iso-gray curves of conjugate harmonic function pairs which define coordinate transformations. Harmonic function pair coordinates render the target curve patterns as parallel lines, which is defined here as linear symmetry. Detecting these lines, or generalized linear symmetry fitting, corresponds to finding invariants of Lie groups of transformations. A technique based on… CONTINUE READING
