Abstract
A method and apparatus for arbitrary transformation of images comprises a transformation between a source image and a destination image. Variables which define the transformation are obtained. A first value and a second value are then determined from the variables. An initial pixel is initialized and destination vectors are determined for the initial pixel. For each remaining pixel to be transformed, the first value is added to the x component and the second value is added to the y component of the destination vectors that correspond to the pixel being transformed. The method and apparatus for arbitrary transformation of images thereby reduces the number of calculations that need to be performed for such operations to two additions only.
