摘要： In learning for pattern recognition, an aggregation of different types of object image data is inputted, and local features having given geometric structures are detected from each object image data inputted. The detected local features are put through clustering, plural representative local features are selected based on results of the clustering, and a learning data set containing the selected representative local features as supervisor data is used to recognize or detect an object that corresponds to the object image data. The learning thus makes it possible to appropriately extract, from an aggregation of images, local features useful for detection and recognition of subjects of different categories.

摘要： An initial core setting device sets the point or area designated by a indication selecting device as a core of area growth. A characteristic amount extraction device extracts a color component value of each pixel of an input image, edge strength value regarding density (lightness), contrast component regarding lightness or texture characteristic amount. A representative color extraction device extracts the color component characteristic amount of the representative color from a point on the initial core. An area dividing device labels as a continuous area the pixel with small difference between one of representative colors and the color component, and generates image dividing data designating individual areas. An area growth/reduction device, in accordance with user's indication, merges into or excludes from an attention area the set initial core area or each point in the area neighbouring the boundary in the area whose shape is changed, based on image characteristic amount or image dividing data. A shape display data generation device generates data for display showing the shape of area which is obtained In the process of (or as a result of) area growth. An image based on generated data for display is superimposed on the input image to be displayed.

摘要： When a dispersion value of a shading value is equal to or more than a threshold value in the neighborhood of a standard point, it is determined that an image pattern has a texture dominant characteristic. When the value is less than the threshold value, a change of the shading value is determined to be moderate (S11). When the dispersion value is equal to or more than the threshold value (S11), a texture characteristic amount is loaded (S12), a characteristic amount suitable for area growth (e.g., texture energy) is calculated (S13), and a distance DT concerning the texture characteristic amount is obtained (S14). When the dispersion value is less than the threshold value (S11), a color component characteristic amount is loaded (S16), a characteristic amount suitable for the area growth (e.g., a characteristic vector obtained from a local histogram concerning a color component or a list of representative color components) is extracted (S17), and a distance DC concerning the color component is obtained (S18). The area is grown based on the corresponding characteristic amount (S15, S19), and a renewal position is determined based on a new borderline of a core area obtained by unifying area growth results from standard points (S20).
