Abstract

Image morphing is often used in film and television industry to create synthetic visual effects by smooth transformation of one object into another. Based upon spatial representation of images, several image morphing techniques have been proposed. Simple spatial techniques, for example cross-dissolve, suffer from lack of smooth transformation while better quality techniques, like mesh warping or field warping, have significant computational complexity. In this paper we present a simple but good quality image morphing technique based upon frequency domain representation of images. Transformation from a source image to a target image takes place by mixing low frequencies of the source image and high frequencies of the target image in varying proportions. The proposed technique has been applied to a wide variety of images. The resulting sequence of images are better in visual quality and faster in execution time.
