Abstract
A method for encoding an image-representative signal, including the following steps: for shapes of the image, applying a transform to a segment of pixels of the shape to obtain a low pass transform component and a high pass transform component; and for segments with an odd number of pixels, including the odd pixel in the low pass transform component and excluding the odd pixel from the high pass transform component.
