Image Registration
for Medical, Remote Sensing,

Image registration is the process of determining the point-by-point correspondence
between two images of a scene. By registering two images, the fusion ofmultimodality
information becomes possible, the depth map of the scene can be determined,
changes in the scene can be detected, and objects can be recognized. Platform: |

Description: 用于检测3D血管图像的分叉点的一个程序，文件夹内还有说明文档，详细介绍了该程序的算法。是用itk库做的一个通用模板类，还有例子。- Branches of tubular structures (vasculature, trachea, neuron, etc.) in medical images are critical for the topology of these
structures. In many applications, It is very helpful to be able to decompose tubular structures and identify every individual
branch. For example, quantification of geometric vascular features, registration of trachea movement due to respiration, tracing of
neuron path. However, manual decomposition can be tedious, time-consuming, and subject to operator bias. In this paper, we
propose a novel method to decompose tubular structures automatically and describe how to implement it in ITK framework. The
input is a 2D/3D binary image that can be obtained from any segmentation techniques, as well as the junctions, which can be
generated automatically from our previously contributed ITK class: itk::JunctionDetectionFilter. The output will be
branches with their labels and their connection. There are only tw Platform: |
