Title:
SYSTEM AND METHOD FOR DETECTING FACIAL FEATURE POINT
Document Type and Number:
WIPO Patent Application WO/2017/171142
Kind Code:
A1
Abstract:
A system and a method for detecting a facial feature point are disclosed. The system for detecting a facial feature point according to an embodiment of the present invention comprises: a learning unit which divides each of a plurality of face images into regions having a predetermined size, learns a correlation between a feature vector of each divided region of the face image and the location of a predetermined feature point in the face image to thereby generate an eigen-codebook, and calculates a regression matrix indicating the correlation from the eigen-codebook; and a detection unit which detects a facial region from a target image, divides the facial region into areas having a predetermined size, detects a feature vector of each divided area of the facial region, and detects the location of a feature point of the facial region by using the detected feature vector and the regression matrix.
