Problems solved by technology

[0003] Although face analysis techniques are continuously improving, many current methods require high computational power or suffer from limited face detection performance
Complications such as faces not positioned directly facing the camera or natural variations in the face (e.g. closed eyes) can adversely affect the results of facial analysis

Abstract

Various methods for local binary pattern based facial feature localization. One example method includes determining an eye state classification of an input image. The example method may also include selecting a texture model for a global shape and an associated mean shape based on eye center positions and the eye state classification, and adjusting locations of feature points defined by the mean shape based on the texture model for the global shape and an associated global shape model. Similar and related example methods and example apparatuses are also provided.

Description

technical field [0001] Embodiments of the present invention relate generally to face recognition technology, and more particularly to methods and apparatus for local binary pattern based facial feature localization. Background technique [0002] Face detection, face recognition and face tracking are being used and applied more and more. The increase in potential applications of facial analysis is due in part to the continuing increase in speed and power of modern microprocessors. Thus, facial analysis can be used in a variety of settings for a variety of applications including biometrics, user interface applications, gaming applications, social networking, and other human-to-human communication applications. Advances in the computing power of microprocessors have also enabled facial analysis functionality to be used on mobile devices such as cell phones and other smart devices. Facial analysis may also be an important development related to motivations such as metadata sta...
