Title: Woo-Han Yun: Innovator in Facial Recognition Technology

Introduction

Woo-Han Yun, an accomplished inventor based in Daejeon, South Korea, has made significant contributions to the field of facial recognition technology. With a total of two patents to his name, Yun's innovations focus on enhancing the accuracy and efficiency of face recognition systems.

Latest Patents

Among Woo-Han Yun's latest patents is a "Face recognition system and method based on adaptive learning." This innovative system includes a specific person detection and tracking unit that identifies and follows a specific individual in a moving image. The facial feature extraction unit then extracts multiple facial feature vectors from the tracked individual. Following this, a face recognition unit cross-references these vectors with previously stored models in a user registration database to find a match. The system also incorporates a learning target selection unit that updates the registration model with selected facial feature vectors, ensuring continual improvement in accuracy.

Another notable patent is the "System and method for verifying face of user using light mask." This system utilizes a facial feature extraction unit to derive a feature vector from images captured by a camera. It generates a non-user Gaussian Mixture Model (GMM) from images stored in a non-user database and a user GMM from images in a user database, enhanced by applying light masks. A log-likelihood value calculation unit then assesses the facial feature vector against both GMMs, with a user verification unit determining the authenticity of the facial image by comparing log-likelihood values against a predefined threshold.
