Abstract: PURPOSE: A medical blood vessel image processing method is provided to clearly display invisible thin blood vessels as well as thick blood vessels by separating blood vessels and non blood vessels. CONSTITUTION: A blood vessel and a non blood vessel are classified based on a local threshold of the blood vessel. A morphology operation is performed to compensate noise included in an image. A blood vessel line is extracted by thinning the image. The direction of the blood vessel line is checked in each area. The most optimal Gabor filter is selectively applied in each area considering the direction and thickness of the measured blood vessel.

Abstract: PURPOSE: A method for restoring infrared vein image blurred by skin scattering is provided to improve the visibility improvement on the medical field. CONSTITUTION: The method for restoring infrared vein image comprises as follows. The image of the blood vessel having relatively dark to the skin is acquired using the near infrared ray irradiation apparatus and infrared camera. The virtual blood vessel image is produced based on the blood vessel thickness of the general man. The unknown parameter of the point distribution function is estimated by the line profile matching between the second vein image and the first vein image. The point distribution function is produced based on the presumed unknown parameter. The first vein image of which boundary is vague is restored by convolution of the point distribution function of the Gaussian.
