A method is presented for finding semi-local projective and affine invariants. The method consists of defining a canonical coordinate system using intrinsic properties of the shape, independently of the given coordinate system. Since this canonical system is independent of the original one, it is invariant and all quantities defined in it are invariant. The method is applied to find local invariants of a general curve with known correspondences of one or two feature points or lines.<>
