Image processing method and apparatus for face image










Image Number 5 for United States Patent #8121408.

An image processing method for a face image is provided. A skin area of a face is segmented from the face image. A brightness histogram of the skin area is generated. A skin shadow point and an eyeball point of the face are extracted from the skin area, the shadow point having a lowest brightness in the skin area. A modified histogram is generated by modifying the brightness histogram so as to correct a specific area having a lower brightness level than the eyeball point at a brightness level of the eyeball point, and to correct a specific portion in the skin area having a higher brightness level than the shadow point at a brightness level of the shadow point. The face image is thresholded in consideration of the modified histogram to produce a binary image or N-level encoded image.
