The invention provides an image processing method and system wherein an image is conceptually textured onto the surface of a three dimensional shape via a projection thereonto. The shape and/or the image position are then moved relative to each other, preferably by a rotation about one or more axes of the shape, and a second projection taken of the textured surface back to the image position to obtain a second, processed image. The view displayed within the processed image will be seen to have undergone an aspect ratio change as a result of the processing. The invention is of particular use in simulating the small movements of humans when speaking, and in particular of processing viseme images to simulate such small movements when displayed as a sequence.
