The paper presents a computational model to extract local symmetry axes corresponding to the areas of homogeneous texture in an image. The approach is to construct an energy functional whose minimizer is a special distance function which attains its maxima at the boundaries between different texture regions and decays away from texture boundaries. Local symmetry axes are extracted from this distance function. The method extends to color texture images. Texture homogeneity is measured using the filter responses of a set of Gabor filters which are derived from dilation and rotation of a single Gabor function.
