METHOD AND APPARATUS FOR HAIR COLOUR SIMULATION

摘要

Method and apparatus are provided that change the colour of a person's hair in a digital color image composed of pixels. The position of t he person's face in the digital image is identified. One or more hair sampling regions are identified based on the expected position of the hair relative t o the position of the face. One or more characteristics of the hair are extracted from the hair sampling region or regions. Pixels in the image are compared with the extracted hair characteristics thereby to detect hair pixels throughout the image. Pixels in the image are also compared with one or more criteria indicating that a pixel is a non-hair pixel thereby allowing detection of non-hair pixels identified in error as hair pixel, A new hair colour is selectively applied to the detected hair pixels, omitting hair pixels identified in erro r.
