Abstract

An imaging system captures images of a human submental profile in a dimension controlled environment and utilizes image analysis algorithms for detecting submental changes. Instead of implementing a strict posture control of a subject, the imaging system allows the subject to freely move his/her head in an up-and-down direction and a high speed camera captures this movement through a series of images at varying head-to-shoulder angles. The image analysis algorithms may accurately compare before and after images at similar head-to-shoulder angles to identify changes in a human submental profile using a series of measurements and checkpoints.

First claim

We claim:

1. A method for identifying a change in a profile comprising:
receiving a plurality of profile images at different head angles caused by vertical tilting of a chin for the profile images, wherein there are at least two sets profile images with the different head angles, a first set comprises before images and a second set comprises after images;
determining an angle for each of the profile images;
matching one of the before images with one of the after images based o…
