摘要： A remote gaze tracking apparatus and method for controlling an Internet Protocol Television (IPTV) are provided. An entire image including a facial region of a user may be acquired using a visible ray, the facial region may be detected from the acquired entire image, and a face width, a distance between eyes, and a distance between an eye and a screen may be acquired from the detected facial region. Additionally, an enlarged eye image corresponding to a face of the user may be acquired using at least one of the acquired face width, the acquired distance between the eyes, and the acquired distance between the eye and the screen, and an eye gaze of the user may be tracked using the acquired eye image.

摘要： A method of processing a blood vessel image is provided. The method includes (a) sharpening an original blood vessel image using a Gabor filter in consideration of various directions and thicknesses of blood vessels included in the blood vessel and (b) detecting edges according to a change in brightness in a blood vessel domain and a non-blood vessel domain of the original blood vessel image and the blood vessel image on which the Gabor filtering step is completed, using an edge extraction method based on a first-order differentiation or second-order differentiation.
