A target place is set in an area of a human body structure having a tree structure in a three-dimensional image. The tree structure of the human body structure is extracted. A path from a reference point set on a branch upstream side of the target place on the tree structure to the target place is determined. Priority is set for respective portions of the tree structure of the human body structure outside the path based on a positional relationship between the portions and the target place. An initial image representing only a portion of the path and images for confirmation of each step sequentially representing the respective portions of the human body structure outside the path according to the priority are generated from the three-dimensional image. The initial image is displayed, and then, the generated images for confirmation of each step are displayed.

A candidate-region for an object-region is set in an image. In a graph including point-S corresponding the object-region, point-T corresponding to a background-region, a point corresponding to each pixel in the image, S-link connecting each pixel and point-S, T-link connecting each pixel and point-T, and N-link connecting each pair of adjacent pixels, a cost is set for each link, graph-cut is performed. Whether a pixel connected to point-S by a link is present in the graph is judged. If no pixel is present, graph-cut is performed at each stage while costs set for all the S-links connecting each pixel in the candidate-region and point-S are increased stepwise in an increment of a predetermined threshold or less until a pixel connected to point-S by a link appears. Whether each pixel in the image belongs to the object-region or the background-region is determined based on a result of graph-cut performed last.

Based on a long diameter of a set specific region, a first region estimated as the specific region and a second region estimated as a background region are set within an input image. Based on a density histogram of each pixel in the first region and a density histogram of each pixel in the second region, a first evaluation value which indicates a likelihood that a density value represents the specific region is calculated for each density value. For each pair of two adjacent pixels within the input image, based on the first evaluation values, a second evaluation value which indicates a likelihood that the two adjacent pixels represent a contour is calculated. Based on the second evaluation value, connection costs between a plurality of nodes respectively representing each pair of the two adjacent pixels are set. The plurality of nodes are connected based on the connection costs.
