Abstract
A novel shape descriptor, chord length function (CLF) which can be obtained by equal arc length partitions of a contour, is proposed. The difference of two shapes is measured by the distance between their corresponding CLF. The proposed CLF is invariant to rotation, scaling and translation. It is robust to noise and simple to compute. Experimental results indicate that CLF is an effective shape descriptor.
