1. A method of manipulating a facial image so as to simulate time-related changes, the method comprising: transforming the facial image to a color space format having intensity and color components, segmenting out the face region using a thresholding procedure wherein the thresholding procedure includes Otsu thresholding: manipulating the facial image to generate a spot change intensity component; manipulating the facial image to generate a wrinkle change intensity component; manipulating the facial image to generate a texture change intensity component; and modifying the intensity component of the facial image based on a combination of the spot change intensity component, wrinkle change intensity component, and texture change intensity component, thereby generating a spot, wrinkle and texture changed facial image; wherein there is further generated a first spot, wrinkle and texture changed facial image which is an aged facial image, and a second spot, wrinkle and texture changed facial image which is a de-aged facial image, wherein the aged or de-aged facial image is selectively blended with the facial image to generate a composite image, and displaying the composite image.
