System and method for determining the position of a hair tail on a body surface

摘要

System and method are provided for determining hair tail positions. An image containing hair which is received from an image acquisition device is processed to find a coarse hair tail position. The coarse hair tail position is refined through further processing. The refined hair tail position may be used for accurate positioning, for example, of hair transplantation tools in various hair transplantation applications.

主权项

1. A method for determining a position of a hair tail on a body surface, comprising:
using a processor to perform one or more of the following steps: determining a contour of a hair from an image of a body surface taken by an imaging device; determining a longitudinal axis of the hair; determining intersection points of the longitudinal axis of the hair and the contour of the hair, wherein one of the intersection points is associated with a coarse position of a hair tail of the hair on the body surface; generating an intensity profile of an image of the hair along the longitudinal axis of the hair; and refining the coarse position of the hair tail based on at least the intensity profile of the image.
