A Statistical Shape Model for the Liver [PDF]
, 2002 The use of statistical shape models is a promising approach for robust segmentation of medical images. One of the major challenges in building a 3D shape model from a training set of segmented instances of an object is the determination of the correspondence between them.

Building a Statistical Shape Model of the Apple from Corresponded Surfaces
Chemical Engineering Transactions, 2015 In this paper, a method for building a 3D statistical shape model of the apple is described. The framework consists of two parts. First, a reference surface is registered to each apple surface, derived from 3D CT scans of apples, of the population to ...

An Annotation-Free Pipeline for 3D Auricular Bowl Atlas Construction and Statistical Shape Modelling from Surface Scans [PDF]
SensorsThree-dimensional (3D) ear morphology is critical for the design of in-the-ear hearing aids, earphones, transcutaneous auricular vagus nerve stimulation (taVNS) electrodes, and auricular reconstruction, yet most existing ear shape models still rely on ...

Diffeomorphic Statistical Shape Models [PDF]
Procedings of the British Machine Vision Conference 2004, 2004 We describe a method of constructing parametric statistical models of shape variation which can generate continuous diffeomorphic (non-folding) deformation fields. Traditional statistical shape models are constructed by analysis of the positions of a set of landmark points.

A Statistical Shape-Based Patient-Specific Anatomical Structure Model
IEEE Access, 2022 A patient-specific anatomical structure model has been widely used in many medical applications. However, in practical applications, to effectively construct a patient-specific anatomical structure model is a challenge, the reasons are: 1) the manual ...

A shape-partitioned statistical shape model for highly deformed femurs using X-ray images
Computer Assisted Surgery, 2022 To develop a patient-specific 3 D reconstruction of a femur modeled using the statistical shape model (SSM) and X-ray images, it is assumed that the target shape is not outside the range of variations allowed by the SSM built from a training dataset.

Camera Motion Agnostic Method for Estimating 3D Human Poses
Sensors, 2022 Although the performance of 3D human pose and shape estimation methods has improved considerably in recent years, existing approaches typically generate 3D poses defined in a camera or human-centered coordinate system. This makes it difficult to estimate

Reliability Estimation for Statistical Shape Models [PDF]
IEEE Transactions on Image Processing, 2008 One of the drawbacks of statistical shape models is their occasional failure to converge. Although visually this fact is usually easy to recognize, there is no automatic way to detect it. In this paper, we introduce a generic reliability measure for statistical shape models. It is based on a probabilistic framework and uses information extracted by the
