| 20080226138 | EYELID DETECTION APPARATUS AND PROGRAM THEREFOR - An eyelid detection apparatus includes edge image generating means for generating an edge image representing a magnitude of pixel value change per pixel in a predetermined direction in a region including an eye, based upon an image of the region; local peak value point searching means for searching a local peak value point, where the magnitude of pixel value change reaches a local peak value in the predetermined direction, in the edge image; and boundary point detecting means for detecting at least one of a first boundary point indicating a boundary between an upper eyelid and an eyeball and a second boundary point indicating a boundary between a lower eyelid and the eyeball, based upon a point which is shifted from the local peak value point in a direction towards the eyeball. | 09-18-2008 |
| 20080226139 | EYELID DETECTION APPARATUS, EYELID DETECTION METHOD AND PROGRAM THEREFOR - An eyelid detection apparatus includes a face-image storing apparatus for storing an image of a face of a subject, an eyelid-candidate extracting apparatus for processing the image stored in the face-image storing apparatus to extract a pair of lines, which becomes a candidate of a combination of a line corresponding to an upper eyelid and a line corresponding to a lower eyelid, a parameter calculating apparatus for calculating a parameter, which indicates a possibility that a pan of the image stored in The face-image storing apparatus, the part corresponding to the pair of lines extracted by the eyelid-candidate extracting apparatus, includes at least one of outer and inner corners of an eye, and an eyelid detecting apparatus for detecting a position of an eyelid of the subject on the basis of the parameter calculated by the parameter calculating apparatus. | 09-18-2008 |
| 20080226175 | APPARATUS, METHOD, AND PROGRAM FOR FACE FEATURE POINT DETECTION - A face feature point detection apparatus includes an image capturing device, an edge calculating unit calculating edge values indicating a luminance change in a direction, and a detection target determining unit scanning an edge image, which is created by arranging the edge values for corresponding pixels based on pixel arrangement of the face images, with an image window being an aggregation of selected pixels formed in a predetermined shape, the detection target determining unit determining a position of the image window having a largest weighted sum of weighted sums to be a detection position where a detection target is present, providing that the weighted sum is calculated by multiplying the edge value which corresponds to each pixel in the image window by a predetermined value defined on a per-pixel basis and adding up all products of the edge value and the predetermined value. | 09-18-2008 |
| 20080232650 | FACE REGION DETECTING DEVICE, METHOD, AND COMPUTER READABLE RECORDING MEDIUM - An image capturing section captures a face of an observed person. A position detecting section detects, from a face image expressing the face captured by the image capturing section, one of a position expressing a characteristic of a nose and a position expressing a characteristic of a region between eyebrows. A computing section computes a past relative position of a predetermined region of the face that is based on the position detected in the past by the position detecting section. A region position detecting section detects a position of the predetermined region on the basis of the past relative position computed by the computing section and the current position detected by the position detecting section. | 09-25-2008 |
| 20090244274 | EYELID OPENING LEVEL DETERMINATION DEVICE AND COMPUTER READABLE MEDIUM STORING COMPUTER PROGRAM THEREOF - An eyelid opening level determination device includes a face image taking unit; an upper eyelid detection unit for detecting an upper eyelid in the face image; a lower eyelid area setting unit for setting an area for searching a lower eyelid based on the upper eyelid; an edge group detecting unit for detecting an edge group where brightness changes from dark to bright as a lower eyelid candidate by scanning the area from an upper side to a lower side; a reliability value obtaining unit for obtaining a reliability value of the edge group; a lower eyelid determination unit in which the edge group having the reliability value exceeding a predetermined value in the edge group is determined to be the lower eyelid; and an eyelid opening level obtaining unit for obtaining opening level of the eyelid based on positions for the upper eyelid and the lower eyelid. | 10-01-2009 |
