Hi everyone,<br><br>I am now trying to extract the regional centers of mass of a labeled image (output of ConnectedComponentImageFilter and RelabelComponentImageFilter). Are there any "direct" ways of doing this?
<br><br>My current plan is to first calculate the bounding boxes of each region using LabelStatisticsImageFilter; and then either manually compute the CoM, or "convert" the region inside the bounding box to image, and use ImageMomentsCalculator to calculate the CoM. I don't know how to do the conversion exactly for the 2nd method. The 2nd method is favored somehow because I might need other attributes from ImageMomentsCalculator such as principal axes.
<br><br>The context: I am currently working on registration using ICP; the extracted centers of mass will serve as inputs to the registration process.<br><br>Your comments are welcomed. Thanks.<br><br>Regards,<br>MC<br>
