| Abstract: | The triple correlation of 2 D image is a complete representation of images. It has the properties of translation invariance and insensitivity to AGN. In this paper, according to the similarity among the vector triangles formed by two indepentent vectors of triple correlation function, the distributions of these two vectors are discussed, so that the triple correlation function based on the triangle form is introduced. The translation rotation scale invariant representation is established by logarithmic mapping of the scaling factor, and FFT transforming of this function.The simulation experiment illustrates the translation rotation scale invariance of invariant representation. |
