Abstract
An image processing method performed by a processor includes: a step of acquiring an image captured of a choroid; a step of performing enhancement processing that enhances contrast in the acquired image; a step of performing binarization processing on the image that has been subjected to the enhancement processing; and a step of extracting a region corresponding to choroidal blood vessels in the choroid from the image that has been subjected to the binarization processing.
Claims18
An image processing method performed by a processor, the method comprising:
- a step of acquiring an image captured of a choroid;
- a step of performing enhancement processing that enhances contrast in the image after it has been acquired;
- a step of performing binarization processing on the image after it has been subjected to the enhancement processing;
- and
- a step of extracting a region corresponding to choroidal blood vessels in the choroid from the image after it has been subjected to the binarization processing.
An image processing device, comprising:
- an image acquisition unit that acquires an image captured of a choroid;
- an enhancement processing unit that performs enhancement processing that enhances contrast in the image after it has been acquired;
- a binarization processing unit that performs binarization processing on the image after it has been subjected to the enhancement processing;
- and
- a region extraction unit that extracts a region corresponding to choroidal blood vessels in the choroid from the image after it has been subjected to the binarization processing.
A non-transitory recording medium storing a program that performs image processing by causing a processor to perform:
- a step of acquiring an image captured of a choroid;
- a step of performing enhancement processing that enhances contrast in the image after it has been acquired;
- a step of performing binarization processing on the image after it has been subjected to the enhancement processing;
- and
- a step of extracting a region corresponding to choroidal blood vessels in the choroid from the image after it has been subjected to the binarization processing.
