Abstract
In a pseudo vascular pattern generation device 10, a processor 11 generates a first image in which white noise has been added to a gray image, generates a second image in which the white noise included in the first image has been diffused, generates a third image in which a blood vessel enhancement filter has been applied to the second image, generates a fourth image in which a region of interest has been set to the third image, and generates a fifth image including the pseudo vascular pattern based on the fourth image.
Claims4
A pseudo vascular pattern generation device comprising:
- a processor that
- generates a first image in which white noise has been added to all of pixels included in a single gray image among a plurality of gray images under a same random number seed,
- generates a second image in which the white noise included in the first image has been diffused by applying a Gaussian filter to the first image,
- generates a third image in which a Frangi filter has been applied to the second image,
- generates a fourth image in which a region of interest has been set to the third image, and
- generates a fifth image including a pseudo vascular pattern by performing geometric transformation on the fourth image.
