Abstract
An apparatus is disclosed for generating frequency component image data representative of image information of a plurality of different spatial frequencies of an image of at least part of a subject from a predefined view. A receiver receives a plurality of images comprising image data representative of a subject from a plurality of view points. For each of a plurality of received images, frequency component image data representative of image information of a plurality of different spatial frequencies within images received by the receiver is determined, and projections of the frequency component image data projected to a predefined view are also determined. Visibility data indicative of the relative visibility of portions of the surface of a subject from viewpoints is then determined. Portions of projections of frequency component image data are associated with the visibility data, and the visibility data associated with portions of projections are utilized to determine frequency component image data representative of frequency image information of an image of a subject from a predefined view.
