Inr tracking with face-to-face and phone app
Medicine, 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.

High-performance face tracking
Proceedings of the 3rd Symposium on Facial Analysis and Animation, 2012 Face tracking is an extensively studied field. Nevertheless, it is still a challenge to make a robust and efficient face tracker, especially on mobile devices. This extended abstract briefly describes our implementation of a high-performance multi-platform face and facial feature tracking system.
