| Summary: | Geometric Morphometries (GMM) is one common approach to shape analysis that
utilizes the coordinates of landmarks to record the relative positions of morphological
points, boundary curves and surfaces as the basis of shape quantification. It is usually
accomplished through a series of steps that can be called the Procrustes Paradigm.
Landmark-Based GMM uses sets of two- or three-dimensional coordinates of biological
landmarks. In this retrospective project, a total of 70 CT-scan images samples (35 male
and 35 female) were selected for the geometric morphometries assessment of sternum by
age and age groups (7 groups). This project was conducted by employing several software
which include Picture Archiving and Communication System (PACS), Medical Imaging
Interaction Toolkit (MITK), MeshLab, Institute for Data Analysis and Visualization
(1DAV) Landmark Software, Notepad++. and MorphoJ. The results of this project suggest
that GMM assessment of sternum by age is more reliable rather than by age group.
However, the level of significance is not really high at only at 45.28% and the Principal
Component Analysis (PCA) on the samples did not show any positive correlation between
shapes of sternum and the age or age group. Thus, it can be concluded that GMM
assessment is not compatible for the classification of sternum shape based on age or age
group. |
