Image data processing apparatus and method, and image data processing program

摘要

When a face image of a character in an image represented by image data fed to a mask data creating apparatus is detected, face image areas of the detected character are respectively extracted by different two types of processing. An appropriate degree is calculated for each of the face image areas extracted by the two types of extraction processing. The face area for which the higher relevance factor is calculated is used, to create mask data.
