Abstract
An image processing apparatus includes: a surface shape estimation unit configured to estimate a surface shape of a target that appears in an intraluminal image of a living body; an imaging viewpoint changing unit configured to change an imaging viewpoint with respect to the surface shape from an imaging viewpoint used for estimation; and an image generation unit configured to generate a virtual image of the target for a case of imaging the target from the changed imaging viewpoint.
Claims21
An image processing apparatus comprising:
- a processor configured to:
- estimate a first surface shape of a target that appears in an intraluminal image of a living body from a first viewpoint;
- change an imaging viewpoint with respect to the first surface shape of the target that appears in the intraluminal image from the first viewpoint to a second viewpoint;
- estimate, based on the first surface shape of the target estimated, a second surface shape of the target for a case of imaging the target from the second viewpoint;
- generate a virtual image of the target for the case of imaging the target from the second viewpoint based on the second surface shape estimated;
- and
- learn a parameter used for recognition of the target based on the virtual image.
An image processing method comprising:
- estimating a first surface shape of a target that appears in an intraluminal image of a living body from a first viewpoint;
- changing an imaging viewpoint with respect to the first surface shape of the target that appears in the intraluminal image from the first viewpoint to a second viewpoint;
- estimating, based on the first surface shape of the target estimated, a second surface shape of the target for a case of imaging the target from the second viewpoint;
- generating a virtual image of the target for the case of imaging the target from the second viewpoint based on the second surface shape estimated;
- learning a parameter used for recognition of the target based on the virtual image.
A non-transitory computer-readable recording medium on which an executable program for an image processing apparatus is recorded, the program instructing a processor of the image processing apparatus to at least execute:
- estimating a first surface shape of a target that appears in an intraluminal image of a living body from a first viewpoint;
- changing an imaging viewpoint with respect to the first surface shape of the target that appears in the intraluminal image from the first viewpoint to a second viewpoint;
- estimating, based on the first surface shape of the target estimated, a second surface shape of the target for a case of imaging the target from the second viewpoint;
- generating a virtual image of the target for the case of imaging the target from the second viewpoint based on the second surface shape estimated;
- and
- learning a parameter used for recognition of the target based on the virtual image.
