Abstract Although numerous studies measure the strengths of perceptual organization cues for grouping contour, most ignore the roles of symmetry and parallel principles in grouping contour. A hierarchy grouping model is developed. Firstly, most saliency edges are extracted as input for subsequent contour grouping. Secondly, the symmetry measure as higher grouping cues which supervises the low level grouping process. Experiments on different types of images show that the model reduces ambiguities in the intermediate representation and have higher efficiency and robustness, while holding biological plausibility.
