In terms of contour-based image retrieval, distance histogram [8] is a method commonly applied for shape description, but it cannot reflect the spatial distribution of contour pixels and different shapes may be with the same distance histogram; so it will lead to a higher false retrieval rate.

Hence, for images polluted by noise, relatively higher false retrieval rate will be resulted in by adopting the DCV algorithm or IDCV algorithm.
