Abstract
A plurality of candidate points are extracted from image data. The plurality of candidate points are normalized, and a set of representative points composing form model that is most similar to set form is selected from the plurality of candidate points. Further, the candidate points and the form model are compared with each other, and correction is performed by adding a region forming structure or by deleting a region, or the like. Accordingly, the structure is detected in image data.
Claims18
A structure detection apparatus for detecting a predetermined structure in image data, the apparatus comprising:
- a candidate point extraction means that extracts a plurality of candidate points belonging to the predetermined structure from the image data;
- a set form storage means that stores, in advance, a set form composed of a plurality of training labels, the set form representing a known form of the predetermined structure;
- a representative point selection means that selects, from the plurality of candidate points extracted by the candidate point extraction means, a plurality of representative points corresponding to the plurality of training labels respectively, the plurality of representative points composing a form model that is the same as or most similar to the set form stored in the set form storage means;
- and
- a structure detection means that detects the predetermined structure in the image data by using the form model composed of the plurality of representative points selected by the representative point selection means, and the plurality of candidate points.
A structure detection method for detecting a predetermined structure in image data, the method comprising the steps of:
- extracting a plurality of candidate points belonging to the predetermined structure from the image data;
- selecting, from the extracted plurality of candidate points, a plurality of representative points corresponding to a plurality of training labels respectively, the plurality of representative points composing a form model that is the same as or most similar to a set form that is composed of the plurality of training labels, the set form representing a known form of the predetermined structure and having been stored in advance in a set form storage means;
- and
- detecting the predetermined structure in the image data by using the form model composed of the selected plurality of representative points, and the plurality of candidate points.
A non-transitory computer-readable recording medium storing therein a structure detection program for causing a computer to execute processing for detecting a predetermined structure in image data, the program comprising the procedures of:
- extracting a plurality of candidate points belonging to the predetermined structure from the image data;
- selecting, from the extracted plurality of candidate points, a plurality of representative points corresponding to a plurality of training labels respectively, the plurality of representative points composing a form model that is the same as or most similar to a set form that is composed of the plurality of training labels, the set form representing a known form of the predetermined structure and having been stored in advance in a set form storage means;
- and
- detecting the predetermined structure in the image data by using the form model composed of the selected plurality of representative points, and the plurality of candidate points.
