IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD |
摘要 |
An image processing device for identifying a characteristic of an eye from a face image comprising: a first differentiation unit configured to differentiate an eye region in a crosswise direction of the eye to obtain a first luminance gradient; a first edge extraction unit configured to extract a first and a second edge points; a voting unit configured to vote for an ellipse; a pupil outline identification unit configured to identify an ellipse expressing a pupil outline; a second differentiation unit configured to obtain a second luminance gradient by differentiating in a vertical direction; a second edge extraction unit configured to extract a third edge point; a curve identification unit configured to identify a curve that fits to the third edge point as a curve expressing an eyelid outline; and a pupil region identification unit configured to identify a pupil region based on the identified ellipse and the identified curve. |
