The filtering unit calculates an evaluation matrix by performing filtering on each pixel position of an image representing a hollow structure using a second order partial differential of a function representing a hollow sphere. The evaluation unit calculates an evaluation value of at least one or more of point-like structureness, line-like structureness, and plane-like structureness at the pixel position based on the calculated evaluation matrix.

1. Technical Field
The present invention relates to an image processing apparatus and method for discriminating a structure of a hollow structure in an image, and a program for causing a computer to perform the image processing method. It is a further object of the present invention to provide an image processing apparatus for discriminating a principal axis direction or a normal direction of a hollow structure in an image.
2. Background Art
FIG. 1 is a schematic block diagram of an image processing apparatus according to a first embodiment of the present invention, illustrating a configuration thereof.
FIG. 2 is a drawing for explaining a multiple resolution transformation.
FIG. 3A is a drawing for explaining a solid sphere model function (part 1).
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic block diagram of an image processing apparatus according to an embodiment of the present invention, illustrating a configuration thereof. The configuration of the image processing apparatus 1 shown in FIG. 1 is realized by executing a program read into an auxiliary storage (not shown) on a computer (e.g., personal computer). The program is provided being recorded on an information storage medium, such as CD-ROM and the like, or distributed via a network, such as the Internet, and installed on a computer.
The image processing apparatus 1 generates a three-dimensional image M0 using a plurality of two-dimensional images captured, for example, by an X-ray CT system 2 and automatically segments a line-like structure and a plate-like structure included in the three-dimensional image M0. The image processing apparatus 1 includes an image obtaining unit 10, a detection region setting unit 20, a discrimination unit 30, a segmentation unit 40, a display unit 50, and an input unit 60.
The image obtaining unit 10 obtains a plurality of CT images (two-dimensional images) captured, for example, by the X-ray CT system 2, and generates a three-dimensional image M0 from the plurality of two-dimensional images. The image obtaining unit 10 may be a unit that obtains two-dimensional images, such as so-called MRI images, RI images, PET images, X-ray images, and the like, as well as CT images.
