Abstract:
A face-image processing apparatus comprising:image input means for inputting an image of a face; multi-value image storing means for storing multi-value image obtained by said image input means; nostril-region extracting means for extracting a nostril multi-valued region from the multi-value image outputted by said multi-value image storing means; eye-region extracting means for extracting a multi-valued eye region extracted from a multi-value image outputted by said multi-value image storing means with using a nostril region extracted by said nostril-region extracting means as a reference point; binarized image storing means for storing a result outputted from said nostril-region extracting means and said eye-region extracting means as a binarized region; and opening/closing determining means for determining opening/closing of the eyes in accordance with a feature of a shape of the binarized eye-region outputted by said binarized image storing means, wherein said nostril-region extracting means extracts a nostril region at which a retrieval is started from a position of a center of gravity of a previous nostril by spirally retrieving a portion surrounding the retrieval start point.
