The Angular Radial transform (ART) is a moment-based image description method adopted in MPEG-7 as a 2D region-based shape descriptor. Efficiency and robustness were demonstrated on binary image. This paper proposes the generalization of the ART to describe two dimensional color images and three dimensional models. First, the ART recommended by the MPEG-7 standard is only limited to binary images and is not robust to perspective deformations. We propose two extensions which allow applying ART… CONTINUE READING
