Apparatus and methods for feathering a composite image
 The invention provides a mechanism and process for feathering a first image and a second image in a composite frame. In this process an original matte image is defined according to the first and second images. A portion of the original matte image is box filtered horizontally and vertically to generate an intermediate matte image. At least a portion of the intermediate matte image is box filtered horizontally and vertically to generate a processed matte image. A composite image including the first image and the second image is then generated according to the box-filtered processed matte image.
