A viewpoint recommendation apparatus includes image feature extraction means for extracting an image feature from the acquired image at a first viewpoint, pose estimation means for calculating a first likelihood map indicating a relation between the estimated pose of the object and a likelihood of this estimated pose, second storage means for storing a second likelihood map indicating a relation between the true first viewpoint and a likelihood of this first viewpoint in the estimated pose, third storage means for storing a third likelihood map indicating a relation between the pose of the object when the object is observed at the first and the second viewpoints and a likelihood of this pose, and viewpoint estimation means for estimating the second viewpoint so that a value of an evaluation function of the first, second, and third likelihood maps becomes the maximum or minimum.

A direction discrimination device includes: an extraction unit configured to extract pieces of feature information from an image of a person, each of the pieces of feature information representing a feature of corresponding one of portions of the person; and a discrimination unit configured to discriminate a direction of the person based on the pieces of feature information. The discrimination unit is configured to weight first feature information which is feature information of a portion that is likely to have a difference in the feature between a first direction and a second direction range, more than second feature information which is feature information of a portion that is less likely to have a difference, in determination of the direction of the person. The second direction range not includes the first direction and includes a second direction opposite to the first direction.

Medical image observation assisting systemincluding CT-image-data retrieving portion, CT-image-data storing portion, information extracting portion, anatomical information DB, point of view/line of view setting portion, luminal organ image generating portion, anatomical nomenclature information generating portion, branch specifying portion, image synthesizing and displaying portionand user I/F control portion. The point of view/line of view setting portionsets a point of view and line of view for observing an external profile of a luminal organ, on the basis of structure information of the luminal organ extracted by the information extracting portion, while a point of interest is kept substantially on a centerline of the organ.
