1. A method of deriving a representation of an image by processing signals corresponding to the image using one or more processors, the method comprising:
- processing the image, or a two dimensional function of the image, using a processor to obtain a two dimensional function of the image at reduced resolution; and
deriving, using a processor, the representation of the image using the reduced resolution two dimensional function of the image.

Abstract
A method and apparatus for deriving a representation of an image by processing signals corresponding to the image is described. The method includes deriving a two-dimensional function (T(d, θ)), such as a Trace transform of the image, and decomposing, for instance by sub-sampling, the two-dimensional function (T(d, θ)) in at least one of its two dimensions, to obtain a reduced resolution Trace transform. The decomposed, two dimensional function is then used to derive the representation of the image.
