Abstract:
1. A method for registering a first graphical representation of a first ear impression with a second graphical representation of a second ear impression, said method comprising: generating a first skeleton of said first graphical representation of said first ear impression, wherein said first skeleton is a line representation of said first graphical representation; generating a second skeleton of said second graphical representation of said second ear impression, wherein said second skeleton is a line representation of said second graphical representation; generating a first feature vector representing a distance and a direction from a point on said first skeleton to a point on a first feature of said first graphical representation; generating a second feature vector identifying a distance and a direction from a point on said second skeleton to a point on a second feature of said second graphical representation; identifying a relationship between a point on said first skeleton and a point on said second skeleton as a function of said first feature vector and said second feature vector; and determining a translation and a rotation of said first feature vector to achieve alignment of said first skeleton with said second skeleton.
