A Hough Transform for Detecting Facial Symmetry Axis

Q Zheng, K Inoue, N Ono… - Journal of the Institute …, 2022 - catalog.lib.kyushu-u.ac.jp
We propose a method for detecting a facial symmetry axis from a frontal face image. The
proposed method adopts a voting procedure like Hough transform that transforms a set of …

Automatic detection of frontal face midline by chain-coded Merlin-Farber Hough trasform

D Okamoio, W Ohyama… - IEEJ Transactions …, 2010 - kyushu-u.elsevierpure.com
We propose a novel approach for detection of the facial midline (facial symmetry axis) from a
frontal face image. The facial midline has several applications, for instance reducing …

Estimating face direction via facial triangle

MG Chung, J Park, J Dong - … Intelligence and Soft Computing-ICAISC 2004 …, 2004 - Springer
In this paper, we propose a vision-based approach to detect a face direction from a single
monocular view of a face by using a facial feature called facial triangle. Specifically, the …

Automatic detection of facial midline as a guide for facial feature extraction

N Nakao, W Ohyama, T Wakabayashi… - … Workshop on Pattern …, 2007 - scitepress.org
We propose a novel approach for the detection of the facial midline from a frontal face
image. The use of a midline as a guide reduces the computation time required for facial …
