Abstract:
1. A method for forming a hairstyle simulation image by combining a face image of a subject and a selected hair image, the method comprising: detecting both eyes in the face image of the subject; forming a semi-oval shaped curve based on a facial width and a line passing through the eyes (hereinbelow referred to as an eye line), the facial width being obtained by multiplying a distance between the eyes by a predetermined multiplier, the semi-oval shaped curve serving as a temporary facial outline below the eye line; detecting left and right edges of a facial outline of the face image by moving the semi-oval shaped curve in left and right directions on the face image to obtain a position of the semi-oval shaped curve which gives a maximum value of the degree of overlap between the semi-oval shaped curve and an edge line of a jaw portion in the face image, and determining left and right edges of the semi-oval shaped curve located at the obtained position, the determined left and right edges of the semi-oval shaped curve being used as the left and right edges of the facial outline of the face image; detecting left and right edges of a facial outline of an original face image of the selected hair image in a manner similar to that for the face image of the subject; and combining the face image of the subject and the selected hair image by homothetically enlarging or reducing the face image of the subject or the selected hair image such that the left and right edges of the facial outline of the face image match the left and right edges of the facial outline of the selected hair image, respectively.
