20080240489 | Feature Change Image Creation Method, Feature Change Image Creation Device, and Feature Change Image Creation Program - A technique for applying a feature of a side attribute to an original image while keeping a principal feature. An image accumulating unit stores images classified into categories per the age or sex. A merging unit selects a category in accordance with an input category. A matching unit matches the input image and each of images included in the selected category with each other, and selects the image having highest degree of similarity. The merging unit merges the input image and the selected image by carrying out the weighted average and so on, and generates and outputs a merged image. | 10-02-2008 |
20080247639 | Data Matching Method, Data Matching Apparatus and Data Matching Program - The purpose is to execute the matching of a data after state change from a data before state change, or the matching of a data before state change from a data after state change. The component analyzing unit realized by software analyzes an input data by using a configuration component of a selected state-specific database and sends the configuration component coefficient to the component coefficient conversion unit. The component coefficient conversion unit converts the sent configuration component coefficient into the configuration component coefficient corresponding to the state-specific database which is not selected and sends it to the state change data generation unit. The state change data generation unit generates the state change data by using the sent configuration component coefficient and the configuration component of the corresponding state-specific database. The matching unit matches the state change data and the registration data accumulated in the matching data accumulating unit. | 10-09-2008 |
20090003710 | Feature Extraction Apparatus, Feature Extraction Method, and Feature Extraction Program - To extract a feature advantageous for classification and correlation by using the information difficult to be acquired even when it is impossible to acquire the information difficult-to-be-acquired from all individuals. Sub-information input device inputs information difficult to be acquired and accumulates the inputted sub-information. Main information input device inputs information easy to be acquired as main information, and accumulates the inputted main information. Sub-information selection device evaluates a category attribution degree of each sub-information accumulated and selects the sub-information of a high category attribution degree. The correlation feature extraction device uses the sub-information selected by the sub-information selection device as the feature extraction filter, and extracts a feature corresponding to the main information from a correlation between the main information and the sub-information. | 01-01-2009 |
20090190821 | PATHOLOGICAL DIAGNOSIS SUPPORT - A pathological diagnosis support apparatus into which a digital color image showing a stained tissue sample is input, the apparatus including: a display that performs a display operation; and an image processor that when the digital color image is input, extracts cell nucleus areas, cytoplasm areas and glandular cavity areas, respectively, based on luminance values of pixels of the digital color image, measures basic feature quantities representing features of shapes of the respective cell nucleus areas, cytoplasm areas and glandular cavity areas, which have been extracted, determines whether or not a particular kind of area that appears in a limited case according to the disease state of the tissue sample exists, for each of the cell nucleus areas, the cytoplasm areas and the glandular cavity areas based on the luminance values and the basic feature quantities, and measures structure feature quantities representing ways in which the cell nucleus areas are positioned, based on the basic feature quantities of the cell nucleus areas, and if the particular kind of area exists, extracts the particular kind of area and makes the display show it together with the structure feature quantities and the cell nucleus areas. | 07-30-2009 |
20110293165 | Epithelial Structure Detector and Related Methods - A method for training a classifier to be operative as an epithelial texture classifier, includes obtaining a plurality of training micrograph areas of biopsy tissue and for each of the training micrograph areas, identifying probable locations of nuclei that form epithelia, generating a skeleton graph from the probable locations of the nuclei that form the epithelia, manually drawing walls on the skeleton graph outside of the epithelia to divide the epithelia from one another, and manually selecting points that lie entirely inside the epithelia to generate open and/or closed geodesic paths in the skeleton graph between pairs of the selected points. Data is obtained from points selected from the walls and the paths and applied to a classifier to train the classifier as the epithelial texture classifier. A method and detector for detecting epithelial structures includes applying a sample micrograph area of biopsy tissue to an epithelial texture classifier; identifying probable locations of nuclei that form epithelia of the sample micrograph area with the epithelial texture classifier, generating a skeleton graph from the probable locations of the nuclei that form the epithelia of the sample micrograph area, determining a set of open and/or closed geodesic paths in the skeleton graph of the sample micrograph area; and determining a set of the epithelial masks using the open and/or closed epithelial paths of the sample micrograph area. | 12-01-2011 |
