This registration method performs a rigid body image to image registration between two vessel structures, using the ICP Algorithm .
Segmentation and centerline extraction for the i2i registration.
Segment out blood vessels from the selected image, then extract the centerline. When finished, set the result as moving or fixed data in the registration tab.
The centerline extraction can take a long time.
Registration of vessel segments to each other.
Select two data sets you want to register to each other, adjust the input parameters. Press the register button to perform vessel based registration between fixed and moving point data, using ICP Algorithm .
The Iterative Closest Point (ICP) Algorithm, also called Vessel Registration, works by iteratively finding the least squares fit between two point data sets, rejecting a fraction of the points during each iteration. This is a local registration, meaning that a local minimum will be found, thus the two data sets should be roughly matching.
