Abstract
An image processing apparatus includes: an abnormality candidate region detection unit that detects an abnormality candidate region based on a contour edge of a mucosal wall or a surface shape of the mucosal wall in an intraluminal image of a body; and an abnormal region specifying unit that specifies an abnormal region based on texture information of the abnormality candidate region.
Claims15
An image processing apparatus comprising:
- an image processor comprising hardware, the image processor being configured to:
- detects an abnormality candidate region based on a contour edge of a mucosal wall or a surface shape of the mucosal wall in an intraluminal image of a body;
- and
- specify an abnormal region based on texture information of the abnormality candidate region,
- wherein the specifying of the abnormal region based on texture information of the abnormality candidate region comprises:
- setting a calculation region for calculation of the texture information;
- calculating the texture information in the calculation region;
- and
- identifying the abnormal region based on the texture information,
- the calculating of the texture information in the calculation region comprises:
- performing normalization in accordance with an imaging distance to the calculation region;
- and
- calculating feature data based on a light absorption change structure in the calculation region, and
- the calculating of the feature data based on the light absorption change structure in the calculation region comprises:
- calculating light absorption change information in the calculation region;
- specifying a ductal structure region based on the light absorption change information;
- and
- specifying a fleck structure region based on the light absorption change information.
