Texture element extraction via cepstral filtering of projections
Rangaraj Mandayam Rangayyan, Antônio César Germano Martins · 2002
This paper presents a method for the extraction of the texton from an image with ordered or quasi-periodic texture, without the assumption of homogeneity of the element. The method includes application of homomorphic or cepstral filtering in the Radon or projection domain. Good approximations to the texton were obtained even when variations are presented in the textured image.
