<P>PROBLEM TO BE SOLVED: To provide an apparatus for extracting image target areas, which stably extracts target areas on images without requiring any external reference even if an imaging environment changes. <P>SOLUTION: According to color images of an RGB color system, color images of an RGR color system and color images of an RRB color system for the enhancement of flesh color are created and converted into those of an L<SP>*</SP>a<SP>*</SP>b<SP>*</SP>color system and then self-mapped by means of a self-organization map (SOM) so as to extract skin color candidate areas. The presence or absence of face parts (eyes, nose, mouth and the like) in face candidate images obtained through the Gabor transform of the skin color candidate areas extracted is detected so as to specify face areas. <P>COPYRIGHT: (C)2007,JPO&INPIT |
