1. A method for registering scans of an object, the method comprising:
- obtaining a first scan of the object from a first perspective;
obtaining a second scan of the object from a second perspective;
extracting features from within each of the first scan and the second scan;
mapping the first scan to a first canonical shape;
mapping the second scan to a second canonical shape; and
registering the first scan and the second scan by matching corresponding extracted features from the first and second canonical shapes.

Abstract
Disclosed is a method for registration of scans of an object, such as a biological organ, by obtaining scans of the object that includes a first scan obtained with the object in a first position and a second scan obtained with the object in a second position different from the first position, extracting landmarks within each of the scans, flattening each of the scans, detecting feature points of each of the flattened scans, matching corresponding feature points of each of the flattened scans, performing a harmonic map registration using the matched corresponding feature points and displaying the registered scans.

8. A method for registering scans of a biological organ, the method comprising:
-
obtaining a first scan with the biological organ in a first position; obtaining a second scan with the biological organ in a second position; extracting anatomical landmarks from within each of the first scan and the second scan; flattening the first scan and the second scan; detecting feature points of each of the flattened first scan and the flattened second scan; matching corresponding feature points from the flattened first scan and the flattened second scan; and performing a harmonic map registration using the matched corresponding feature points. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A system for registering scans of an object, the system comprising:
-
a scanner that obtains a first scan of the object from a first perspective and obtains a second scan of the object from a second perspective; a memory for storing the first scan and the second scan; and a processor that extracts landmarks from within each of the first scan and the second scan, flattens the first scan and the second scan, detects feature points from each of the flattened first scan and the flattened second scan, matches corresponding feature points of each of the plurality of flattened scans from the flattened first scan and the flattened second scan, and performs a harmonic map registration using the matched corresponding feature points. - View Dependent Claims (19)
