Estimating Sit-to-Stand Dynamics Using a Single Depth Camera.
Matthew RP, Seko S, Bailey J, Bajcsy R, Lotz J. Matthew RP, et al. IEEE J Biomed Health Inform. 2019 Nov;23(6):2592-2602. doi: 10.1109/JBHI.2019.2897245. Epub 2019 Feb 4. IEEE J Biomed Health Inform. 2019. PMID: 30716057
This paper presents and validates a method for estimating dynamic effects such as joint torques and body momenta using a single depth camera. An allometrically scaled, sagittal plane dynamic model is used to estimate the joint torques at the ankles, knees, hips, and low ba …

Kinematic and Kinetic Validation of an Improved Depth Camera Motion Assessment System Using Rigid Bodies.
Matthew RP, Seko S, Bajcsy R, Lotz J. Matthew RP, et al. IEEE J Biomed Health Inform. 2019 Jul;23(4):1784-1793. doi: 10.1109/JBHI.2018.2872834. Epub 2018 Oct 1. IEEE J Biomed Health Inform. 2019. PMID: 30281504
High-end motion capture systems, however, are expensive and require dedicated camera spaces with lengthy setup and data processing commitments. Depth cameras, such as the Microsoft Kinect, provide an inexpensive, marker-free alternative at the sacrifice of joint-pos …

Surgical Coaching from Head-Mounted Video in the Training of Fluoroscopically Guided Articular Fracture Surgery.
Karam MD, Thomas GW, Koehler DM, Westerlind BO, Lafferty PM, Ohrt GT, Marsh JL, Van Heest AE, Anderson DD. Karam MD, et al. J Bone Joint Surg Am. 2015 Jun 17;97(12):1031-9. doi: 10.2106/JBJS.N.00748. J Bone Joint Surg Am. 2015. PMID: 26085538 Review.
METHODS: Fifteen first-year or second-year orthopaedic surgery residents reduced and fixed a standardized intra-articular tibial plafond fracture model under fluoroscopic guidance. Their performances were recorded by a head-mounted video camera. Prior to repeating the proc …

Imaging high-dimensional spatial entanglement with a camera.
Edgar MP, Tasca DS, Izdebski F, Warburton RE, Leach J, Agnew M, Buller GS, Boyd RW, Padgett MJ. Edgar MP, et al. Nat Commun. 2012;3:984. doi: 10.1038/ncomms1988. Nat Commun. 2012. PMID: 22871804 Free PMC article.
Here we show that modern electron-multiplying charge-coupled device cameras can measure correlations in both position and momentum across a multi-pixel field of view. This capability allows us to observe entanglement of around 2,500 spatial states and demonstrate Einstein- …

Tourism-supported working lands sustain a growing jaguar population in the Colombian Llanos.
Hyde M, Payán E, Barragan J, Stasiukynas D, Rincón S, Kendall WL, Rodríguez J, Crooks KR, Breck SW, Boron V. Hyde M, et al. Sci Rep. 2023 Jun 27;13(1):10408. doi: 10.1038/s41598-023-36935-2. Sci Rep. 2023. PMID: 37369714 Free PMC article.
Jaguars (Panthera onca) are one such species whose population trends and survival rates remain unknown across working lands. We integrated nine years of camera trap data and tourist photos to estimate jaguar density, survival, abundance, and probability of tourist sighting …
