Two dimensional discrete statistical shape models construction

چکیده
In this paper, we present a discrete approach to 2D statistical shape models construction. An object is modeled in terms of landmark points on its contour. An optimized process of intrinsic discrete properties computes then curvilinear position, curvature and normal vector for each point. The approach uses after a dynamic programming process to match points of different shapes. By identifying matched points on a set of training examples, a statistical approach with principal component analysis, computes the mean object shape, the major modes of shape variation and extracts a compact and generic model.

Three-dimensional point distribution models for tubular objects
Landmark based statistical shape models are becoming increasingly popular in medical image analysis. These models require a set of training shapes in which corresponding landmarks are indicated. If a limited number of training shapes is available while a large number of landmarks is needed to describe a shape properly, a model based on observations in the training set alone may be too restricte...
متن کاملDiscrete Element Modeling of Dynamic Compaction with Different Tamping Condition
Dynamic Compaction (DC) is a common deep compaction method that is usually used for densification of coarse-grained soils. Although traditional continuum-based models such as the Finite Element Method can be successfully applied for assessment of stress distributions or deformations induced by DC, they are typically not adequate for capturing the grain scale mechanisms of soil behavior under im...
متن کاملAutomated Construction of 3d Statistical Shape Models
Automated segmentation of medical images is a difficult task because of the complexity of anatomic structures, inter-patient variability, and imperfect image acquisition. Prior knowledge, in the form of pointbased statistical shape models (point distribution models) of a structure of interest can greatly assist segmentation to robustly find the structure in a patient’s image. Point distribution...
متن کاملA Hypothesis Testing Framework for High-Dimensional Shape Models
Statistical shape models are powerful tools for describing anatomical structures and are increasingly being used in a wide variety of clinical and biological contexts. One of the promising applications of this technology is the testing of hypotheses that entail shape differences, and visualization of those differences between cohorts. Statistical testing of shapes, however, is difficult due the...
متن کاملThe Hamming Ball Sampler
We introduce the Hamming ball sampler, a novel Markov chain Monte Carlo algorithm, for efficient inference in statistical models involving high-dimensional discrete state spaces. The sampling scheme uses an auxiliary variable construction that adaptively truncates the model space allowing iterative exploration of the full model space. The approach generalizes conventional Gibbs sampling schemes...
