Hierarchical Eyelid and Face Tracking [PDF]

open access: yes, 2007
Most applications on Human Computer Interaction (HCI) require to extract the movements of user faces, while avoiding high memory and time expenses. Moreover, HCI systems usually use low-cost cameras, while current face tracking techniques strongly depend on the image resolution.

Inr tracking with face-to-face and phone app

open access: yesMedicine, 2023
Background: Warfarin has a narrow therapeutic window. Maintaining the patient’s international normalized ratio (INR) within a predefined therapeutic range is one of the main challenges of warfarin treatment. This study aimed to compare the INR values of patients followed by face-to-face and telephone applications.

A gaze prediction technique for open signed video content using a track before detect algorithm [PDF]

open access: yes, 2008
This paper proposes a gaze prediction model for open signed video content. A face detection algorithm is used to locate faces across each frame in both profile and frontal orientations. A grid-based likelihood ratio track before detect routine is used to
