MAHECHA, Vivianne A. Implementation of hypercomplex or quaternion numbers in color image. Ing. Desarro. [online]. 2008, n.23, pp.72-83. ISSN 0122-3461.

Working an image represented in the space of quaternion numbers allows it to be transform as a whole. In this case the image processing becomes more precisely as it is show in this article with an implementation of an edge detection system of a color image.

Palavras-chave : Quaternion; quaternion Fourier transform; Sobel operator.
