1. A method of encoding a general arbitrary image feature in a video image frame, the image feature including pixels that each have a pixel value and a non-binary transparency value, the method comprising the steps:

  • applying a threshold filter to the non-binary transparency values to form a binary representation of shape of the image feature;

    shape coding the binary shape of the image feature; and

    texture coding the non-binary transparency values of the image feature separately from the binary shape.
