There is provided an information processing apparatus and method capable of more easily comparing 3D objects. Comparison information which is information for displaying a plurality of 3D objects of 6DoF content in a comparable manner is generated. Further, the plurality of 3D objects of the 6DoF content is displayed in a comparable manner on the basis of comparison information which is information for displaying the plurality of 3D objects in a comparable manner. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, an information processing system, and the like.

Embodiments of the present disclosure provide a software program that displays both a volume as images and segmentation results as surface models in 3D. Multiple 2D slices are extracted from the 3D volume. The 2D slices may be interactively rotated by the user to best follow an oblique structure. The 2D slices can “cut” the surface models from the segmentation so that only half of the models are displayed. The border curves resulting from the cuts are displayed in the 2D slices. The user may click a point on the surface model to designate a landmark point. The corresponding location of the point is highlighted in the 2D slices. A 2D slice can be reoriented such that the line lies in the slice. The user can then further evaluate or refine the landmark points based on both surface and image information.

Methods are disclosed for the generation and editing of layer delineations within three-dimensional tomography scans. Cross sections of a subject are generated and presented to an operator, who has the ability to edit layer delineations within the cross section, or determine parameters used to generate new cross sections. By guiding an operator through a set of displayed cross sections, the methods can allow for a more rapid, efficient, and error-free segmentation of the subject. The cross sections can be nonplanar in shape or planar and non-axis-aligned. The cross sections can be restricted to exclude one or more user-defined regions of the subject, or to include only one or more user-defined regions of the subject. The cross sections can be localized to a point-of-interest. Iterative implementations of the methods can be used to arrive at a segmentation deemed satisfactory by the user.

An image processing apparatus, an image display system, an image processing method, and a program by which it is possible to display an optimum three dimensional image when display is switched from a two dimensional tomographic image to a three dimensional image are provided. The processor (14) outputs a tomographic image display signal representing a two dimensional tomographic image included in a first tomographic image group based on first imaging data obtained by imaging a subject, extracts a second tomographic image group having a smaller interval between tomographic images than the first tomographic image group, on the basis of second imaging data acquired in imaging corresponding to the imaging for acquiring the first imaging data, if a display switching signal indicating switching from display of the two dimensional tomographic image to display of a three dimensional image is acquired, and outputs a three dimensional image display signal representing a three dimensional image generated on the basis of the extracted second tomographic image group.
