Abstract
An image processing method performed by a processor and including: a step of acquiring a choroidal vascular image; a step of detecting a vortex vein position from the choroidal vascular image; a step of identifying a choroidal vessel related to the vortex vein position; and a step of finding a size of the choroidal vessel.
Claims8
An image processing method performed by a processor, the image processing method comprising:
- a step of acquiring a choroidal vascular image;
- a step of detecting positions of a first vortex vein and a second vortex vein from the choroidal vascular image;
- and
- a step of identifying a first pixel group associated with the first vortex vein and a second pixel group associated with the second vortex vein in the choroidal vascular image, based on a boundary line that is determined based on position information related to the first vortex vein and the second vortex vein, from pixels on a choroidal vessel.
