About

Fok Hing Chi Tivive’s research centers on facial expression recognition, a cornerstone of affective computing and human-computer interaction. His work focuses on developing robust, automated systems to decode emotional states from static facial images, addressing a critical need in fields ranging from perceptual interfaces to robotics and online gaming. A key contribution is his exploration of feature selection methods to isolate the most discriminative visual cues for expressions like happiness, surprise, and anger, as demonstrated in his 2010 paper on feature selection for facial expression recognition (22 citations). He also advanced the practical challenge of distinguishing subtle expressions, such as smiling from neutral faces, with an automatic recognition system (14 citations). Notably, Tivive introduced a novel hybrid approach combining trainable 2-D filters with support vector machines, improving classification accuracy by learning optimal filters directly from data (4 citations). While his citation counts are modest, his work provides foundational techniques for efficient, real-world expression analysis, contributing to the evolution of more perceptive and emotionally aware interactive systems.
