Statistical linear models in Procrustes shape space
The configuration matrix of a set of labeled landmarks is one the most used shape representations. However, it is well-known that the configuration matrix is not invariant under translation, scaling and rotation. This problem is revisited in this work where a local tangent shape space characterization at a reference shape is obtained as the null space of the subspace spanned by the reference sh...
متن کاملGait recognition based on Procrustes shape analysis
Gait recognition has recently attracted increasing attention, especially in vision-based human identification at a distance in visual surveillance. This paper proposes a simple but efficient gait recognition algorithm based on statistical shape analysis. For each gait sequence, a background subtraction procedure is used to segment spatial silhouettes of the walking figures from the background. ...
متن کاملContinuous Generalized Procrustes analysis
Two-dimensional shape models have been successfully applied to solve many problems in computer vision, such as object tracking, recognition, and segmentation. Typically, 2D shape models are learned from a discrete set of image landmarks (corresponding to projection of 3D points of an object), after applying Generalized Procustes Analysis (GPA) to remove 2D rigid transformations. However, the st...
متن کاملHyperbolic Space
Radial lines, suitably parameterized, are geodesics, but notice that the distance from the origin to the (Euclidean) unit sphere is infinite. This model makes it intuitively clear that the boundary at infinity of hyperbolic space is Sn−1. Hyperbolic space together with its boundary at infinity has the topology of a closed ball, and isometries of hyperbolic space extend uniquely to a homeomorphi...
متن کاملProcrustes Analysis in Fetal Alcohol Syndrome diagnosis
The unique facial appearance associated with fetal alcohol syndrome (FAS) is emphasised in diagnosis, which relies, in part, on the comparison of linear measurements of facial features to population norms. We explore the use of shape analysis as an alternative diagnostic tool for FAS. This paper implements General Procrustes Analysis to compare the FAS facial shape with the normal facial shape....
