1. An animation processor comprising a processor, an instruction memory, a working memory, inputs and outputs, and comprising: an input for receiving an input animation sequence comprising a plurality of time-sequenced frames; storage for a style image pair, comprising an input style image and an output style image, wherein differences between the input style image and the output style image define a style for drawings and other visual elements; logic for generating an image orientation field for each time-sequenced frame from image data within the respective time-sequenced frame; logic for generating a style orientation field defined in a coordinate system of the input style image and the output style image; logic for calculating a velocity field from the time-sequenced frames; logic for generating an output animation sequence comprising output images that has temporal coherence and that takes on the style defined by the style image pair by using the image orientation fields, the style orientation field, and the velocity fields; and an output for outputting the output animation sequence.
12. The animation processor of claim 1 , further comprising logic for adjusting object boundaries based on variations between points in the output style image and points in the input style image.
