Method and apparatus for recognizing a protrusion on a face
First Claim
Patent Images
1. A method for recognizing a protrusion on a face, comprising:
- forming a first image of a target in a condition in which the target is lighted and a second image of the target in a condition in which the target is non-lighted to obtain two images of the target;
detecting a face region from the first image and a face region of the second image from the second image, respectively;
comparing the face regions detected from the first and second images;
analyzing a change of contrast in the face regions; and
determining a protruding degree of a face corresponding to the first and second images based on the result of the analyzing.

Abstract
A method and apparatus for recognizing a protrusion on a face is proposed. The apparatus forms two images, wherein one is formed in a condition in which a target is lighted and another is formed in a condition in which the target is non-lighted. Face regions are detected from the images respectively and then are compared each other. Then, analyzing change in intensity for indicating change in contrast of the compared regions is performed. Based on the result of the analyzing, it is determined whether there is a protrusion in a face presented in the images.
