MIMU sensors for joint kinematic estimation: anatomical landmarking and frame correction
… study explores the possibility of anatomical landmarking using a single camera and a pointer apparatus. Results showed anatomical landmark position could be determined using a single camera, as the anatomical landmarks found from this study and a camera-based system showed similar results. …

Modeling of Aortic Valve Anatomic Geometry from Clinical Multi Detector-Row Computed Tomography Images
… and prone to error because of the manual landmarking step, so we created a novel method to perform automatic landmarking of training data. Our method used high dimensional warping (HDW) to propagate landmarks from a template model. We used this landmarking method to create point …

From Bones to Bytes
… it investigates sex-related variation, automated landmarking, and inter-species discrimination under conditions typical of archaeological material. The first part analyses osteometric measurements using machine learning methods to classify and explore sex-related structure in bone data. Supervised …

An automated computer-assisted approximation of the nose in South Africans from CBCT (Cone Beam Computed Tomography) scans
… were performed using an automatic dense landmarking procedure and analysed by geometric morphometrics. In this research, a validation of the precision of the automatic placement of landmarks, demonstrated its utilisation as a convenient prerequisite for geometric morphometric based shape …

Magnitude and reproducibility of smiling in 12-year-old Caucasian children in the Republic of Ireland: a comparison of Class I and Class II malocclusions
… Landmark identification error was assessed by re-landmarking 10 percent of the images, one month after initial landmarking. The magnitude of movement from rest to posed smile and from rest to maximal smile averaged over all the landmarks was calculated for each session. Results: The magnitude of …

The immediate effects of aligners and aesthetic fixed appliances on smiling and perceptions in young adults
… had 26 landmarks placed by 1 operator. The landmarking identification error was calculated by re-landmarking 10 percent of the original sample one month after initial images were landmarked and determining the difference in landmark placement. The mean magnitude of movement and …

Three-Dimensional Body Volume Measurement From Two-Dimensional Images: Towards A Smartphone Application
… both shape and pose and to use automatic landmarking methods. Regarding a pathway to a smartphone app, camera parameter information should be considered to improve processing of the images and smartphone orientation information should be considered to correct for distortions due to a …

Assessing primate skull shape variation in relation to habitat: a 3D geometric morphometric approach
… methodology. This was achieved through trials of landmarking and statistical procedures on various data processing software, e.g. Checkpoint, TINA, and MeshLabs. Ultimately, the R Project software and accompanying IDE, R Studio, was used to collect, process and analyse the specimen shape data. …

How the Heart Grows: From Multi-scale Data to a Multi-scale Model
… modelling. Finite element modelling, anatomical landmarking and temporal staging generated a dynamic shape model of the C-looping heart which provided the basis to link the cellular, tissue, and organ levels. At the cellular level the developed workflow, which consisted of various parts including …
