Abstract:
Methods for performing genetic algorithm-based feature selection are provided herein. In certain embodiments, the methods include steps of applying multiple data splitting patterns to a learning data set to build multiple classifiers to obtain at least one classification result; integrating the at least one classification result from the multiple classifiers to obtain an integrated accuracy result; and outputting the integrated accuracy result to a genetic algorithm as a fitness value for a candidate feature subset, in which genetic algorithm-based feature selection is performed.
Abstract:
A method of automatically identifying the microarray chip corners and probes, even if there are no probes at the corners, in a high density and high resolution microarray 5 scanned image having an image space, wherein the method minimizes the error distortions in the image arising in the scanning process by applying to the image a multipass corner finding algorithm comprising: (a) applying a Radon transform to an input microarray image to project the image into an angle and distance space where it is possible to find the orientation of the straight lines; (b) applying a fast Fourier transform to the projected image 10 of (a) to find the optimal tilting angle of the projected image; (c) determining the optimal first and last local maxima for the optimal tilting angle; (d) back projecting the determined first and last local maxima to the image space to find the first approximation of the first and last column lines of the image; (e) rotating the image and repeating steps (a) through (d) to find the first approximation of the top and bottom row lines of the image; (f) determining 15 the first approximation of the four corners of the image from the intersection of the column and row lines; (g) applying a heuristic for determining if the first approximation of step (f) is sufficient; and (h) optionally trimming the scanned image around the first approximation of the four corners and repeating steps (a) through (f).
Abstract:
Photo or video content of a person is acquired (401). A dimension of at least one iris of a person such as radius of the iris is measured (405, 411). A dimension of the face of the person, such as width of the face, is measured. The person is then classified (413) as an adult or child on the basis of a ratio of the dimension of the face and the dimension of the iris.

Abstract:
There is provided an apparatus (100) for indexing video data objects (110), said apparatus (100) comprising an input (110) for receiving the video data objects, and a processor (150, 160, 170, 180) for analyzing the video data objects (110) to identify therefrom occurrences of different categories of shots or segments (10, 20, 30) therein, each shot or segment (10, 20, 30) comprising a sequence of one or more images, each shot or segment (10, 20, 30) being identified in response to image feature content of its one or more images, said processor (150, 160, 170, 180) being operable to process the video data objects (110) based on at least the occurrences of the different categories of shots or segments (10, 20, 30) to provide video index classifications of the video data objects (110).
Abstract:
This invention relates to a method and computer system for automatic generation of trailers. More specifically it relates to a method for generating revenues from providers of content data. The method generally comprises the steps of finding product placement data in a super set of data. When these product placements have been found they are preferably matched with a user profile and segments, of the superset comprising these product placements with a positive match, are selected and merged into a subset of data. A counter may keep track of which product placement that has been chosen and how many times a product placement has been chosen and viewed. Based on the value of the counter an invoice is created.
Abstract:
A method and system for generating a personalized summary of content for a user is provided that include determining personality attributes of the user; extracting features of the content; and generating the personalized summary based on a map of the features to the personality attributes. The features may be ranked based on the map and the personality attributes, where the personalized summary includes portions of the content having the features which are ranked higher than other features. The personality attributes may be determined using Myers-Briggs Type Indicator test, Merrill Reid test and/or brain use test, for example.
Abstract:
This invention relates to a method and device for case-based decision support. It proposes that a case-based decision support system is trained on inputs from several radiologists in order to have a "baseline" system, and then the system provides an option to a radiologist to refine the baseline system based on his/her inputs which either refine weights of features for similarity distance computation directly or provide new similarity ground truth clusters. By enabling modifying the similarity distance computation based on user inputs, this invention adapts similarity ground truth to different users with different experience and/or different opinions.
Abstract:
The invention relates to search for cases in a database. According to the proposed method and apparatus, similarity matching is performed between an input case and a set of cases in an initial search to receive similar cases by- using a given matching criterion. Then statistics on image and non- image-based features associated with the similar cases are calculated and presented to the user with the similar cases. In a search refinement the similar cases are refined by additional features that are determined by the user based on the statistics. The search refinement can be iterative depending on the user's need.
Abstract:
The invention relates to a method for assisting a clinician in determining a cancer diagnosis. The method comprises analyzing gene copy numbers obtained from for example from gene chips. The gene copy numbers are analyzed in order to derive or extract genome features which emphasize abnormal gene copy numbers of the genome. Various methods may be used for extracting such genome features. By using a classifier, the genome features can be classified in order to determine a medical outcome which can be used by a clinician for making a diagnosis.
