On the problems of describing joint axis alignment
Journal of Biomechanics, 2008Each three-dimensional joint possesses at least one potentially oblique axis of rotation. Several systems are used to express joint axis alignment. One system, designated the plane projection (PP) method, describes angles based on orthogonal projections onto two, of the three, anatomical planes.

Proceedings of the 1st ACM International Conference on Multimedia Retrieval, 2011
In this paper, a joint active appearance model (joint-AAM) framework is proposed for face alignment. The object function consists of more than one active appearance model and some constraint items. It can be optimized through the efficient project-out inverse compositional (POIC) fitting algorithm. By transferring the low dimensional parameter space to

Joint Spatio-Temporal Alignment of Sequences
IEEE Transactions on Multimedia, 2013Video alignment is important in different areas of computer vision such as wide baseline matching, action recognition, change detection, video copy detection and frame dropping prevention. Current video alignment methods usually deal with a relatively simple case of fixed or rigidly attached cameras or simultaneous acquisition. Therefore, in this paper

Joint Graph Embedding and Alignment with Spectral Pivot
Proceedings of the 27th ACM SIGKDD Conference on Knowledge Discovery & Data Mining, 2021Graphs are powerful abstractions that naturally capture the wealth of relationships in our interconnected world. This paper proposes a new approach for graph alignment, a core problem in graph mining. Classical (e.g., spectral) methods use fixed embeddings for both graphs to perform the alignment.

Subtalar joint alignment in ankle osteoarthritis
Foot and Ankle Surgery, 2019Although it has been proposed that in mid-stage ankle osteoarthritis, the subtalar joint can compensate for deformities above the ankle joint, the evidence is weak. We thus investigated subtalar joint alignment in different stages of ankle osteoarthritis using weightbearing computed tomography (CT) scans.The subtalar joint of 88 patients with ...

Domain Generalization by Joint-Product Distribution Alignment
Pattern Recognition, 2023In this work, we address the problem of domain generalization for classification, where the goal is to learn a classification model on a set of source domains and generalize it to a target domain. The source and target domains are different, which weakens the generalization ability of the learned model.

Joint Cascade Face Detection and Alignment
2014We present a new state-of-the-art approach for face detection. The key idea is to combine face alignment with detection, observing that aligned face shapes provide better features for face classification. To make this combination more effective, our approach learns the two tasks jointly in the same cascade framework, by exploiting recent advances in ...

Kinematically aligned TKA can align knee joint line to horizontal
Knee Surgery, Sports Traumatology, Arthroscopy, 2016The joint line of the native knee is horizontal to the floor and perpendicular to the vertical weight-bearing axis of the patient in a bipedal stance. The purposes of this study were as follows: (1) to find out the distribution of the native joint line in a population of normal patients with normal knees; (2) to compare the native joint line ...

Single-Stage Joint Face Detection and Alignment
2019 IEEE/CVF International Conference on Computer Vision Workshop (ICCVW), 2019In practice, there are huge demands to localize faces in images and videos under unconstrained pose variation, illumination change, severe occlusion and low resolution, which pose a great challenge to existing face detectors. This challenge report presents a single-stage joint face detection and alignment method.

Joint clustering and alignment for nucleosome occupancy analysis
2012 IEEE International Conference on Bioinformatics and Biomedicine Workshops, 2012Several studies show that nucleosome occupancy patterns around transcription starting sites provide evolutionary and regulatory information about genes. However, as transcription starting sites may not accurately reflect physical nucleosome occupancy patterns, clustering of nucleosome occupancy patterns centered at transcription starting sites may give
