Abstract
An image processing apparatus obtains a plurality of moving images of a predetermined site of an eye, specifies a vascular region by using at least one moving image of the plurality of moving images, and measures the sizes of blood cell aggregates in a specific vascular branch in the specified vascular region for each moving image of the plurality of moving images.
Claims34
An image processing apparatus comprising:
- an image obtaining unit configured to obtain a plurality of moving images of a predetermined site in an eye area;
- a specifying unit configured to specify a vascular region by using at least one moving image of the plurality of moving images;
- and
- a measuring unit configured to measure a blood cell aggregate size in a specific vascular branch in the specified vascular region in each moving image of the plurality of moving images.
An image processing method comprising:
- an image obtaining step of obtaining a plurality of moving images of a predetermined site in an eye area;
- a specifying step of specifying a vascular region using at least one moving image of the plurality of moving images;
- and
- a measuring step of measuring a blood cell aggregate size in a specific vascular branch in the specified vascular region in each of the plurality of moving images.
A non-transitory computer readable storage medium storing a program for causing a computer to execute an image processing method, the method comprising:
- an image obtaining step of obtaining a plurality of moving images of a predetermined site in an eye area;
- a specifying step of specifying a vascular region using at least one moving image of the plurality of moving images;
- and
- a measuring step of measuring a blood cell aggregate size in a specific vascular branch in the specified vascular region in each of the plurality of moving images.
An image processing apparatus comprising:
- an image obtaining unit configured to obtain a moving image of an eye area;
- a specifying unit configured to specify a vascular region by using the moving image;
- and
- a determining unit configured to determine a vascular branch based on the vascular bifurcations in the specified vascular region.
An image processing method comprising:
- an image obtaining step of obtaining a moving image of an eye area;
- a specifying step of specifying a vascular region using the moving image;
- and
- a determining step of determining a vascular branch based on the vascular bifurcations in the specified vascular region.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute an image processing method, the method comprising:
- an image obtaining step of obtaining a moving images of an eye area;
- a specifying step of specifying a vascular region using the moving image;
- and
- a determining step of determining a vascular branch based on the vascular bifurcations in the specified vascular region.
