Pain Intensity Estimation from Mobile Video Using 2D and 3D Facial Keypoints

no code implementations17 Jun 2020 Matthew Lee, Lyndon Kennedy, Andreas Girgensohn, Lynn Wilcox, John Song En Lee, Chin Wen Tan, Ban Leong Sng

Our contributions are adata collection study with post-surgical patients to collect ground-truth labeled sequences of 2D and 3D facial keypoints for developing a pain estimation algorithm, a pain estimation model that uses multiple instance learning to overcome inherent limitations in facial keypoint sequences, and the preliminary results of the pain estimation model using 2D and 3D features with comparisons of alternate approaches.

LOH and behold: Web-scale visual search, recommendation and clustering using Locally Optimized Hashing

no code implementations21 Apr 2016 Yannis Kalantidis, Lyndon Kennedy, Huy Nguyen, Clayton Mellina, David A. Shamma

We propose a novel hashing-based matching scheme, called Locally Optimized Hashing (LOH), based on a state-of-the-art quantization algorithm that can be used for efficient, large-scale search, recommendation, clustering, and deduplication.
