  • Patent number: 7643686
    Abstract: In a method for classifying a sequence of records into events based upon feature values, such as time and/or location, associated with each of the records, feature differences between consecutive records are determined. The feature differences are ranked. A sequence of three or more clusters of feature differences is computed. The clusters are arranged in decreasing order of relative likelihood of respective feature differences representing separations between events. The records can be inclusive of images.

  • Publication number: 20090299999
    Abstract: A method for facilitating semantic event classification of a group of image records related to an event. The method using an event detector system for providing: extracting a plurality of visual features from each of the image records; wherein the visual features include segmenting an image record into a number of regions, in which the visual features are extracted; generating a plurality of concept scores for each of the image records using the visual features, wherein each concept score corresponds to a visual concept and each concept score is indicative of a probability that the image record includes the visual concept; generating a feature vector corresponding to the event based on the concept scores of the image records; and supplying the feature vector to an event classifier that identifies at least one semantic event classifier that corresponds to the event.

  • Publication number: 20090297032
    Abstract: A system and method for semantic event detection in digital image content records is provided in which an event-level “Bag-of-Features” (BOF) representation is used to model events, and generic semantic events are detected in a concept space instead of an original low-level visual feature space based on the BOF representation.

  • Publication number: 20090094518
    Abstract: A method for image presentation are provided, in which at least one theme for image presentation is obtained; at least one set of images is acquired for presentation in association with each theme; and a presentation area image is generated for presentation on a display with a plurality of separate presentation objects in the presentation area image; an image value for each of the acquired images is determined; an emphasis score is determined for each of the acquired images. The presentation area image is presented with one of the acquired images in each of the presentation objects; and the presentation objects are animated by moving the presentation objects relative to each other in a manner that attracts more attention to presentation objects that are used to present images having a higher emphasis score than presentation objects that are used to simultaneously present images having a lower emphasis score.

  • Publication number: 20080205772
    Abstract: In a computer-mediated method for providing representative images, image records are classified spatio-temporally into groups. In each group, image records are partitioned into clusters and the hierarchically highest cluster is ascertained. The partitioning is between a hierarchy of feature clusters and a remainder cluster, based on a predetermined plurality of saliency features. Feature clusters each have one or more of the saliency features. The remainder cluster lacks the saliency features. Feature clusters are each exclusive of the saliency features of any higher clusters in the hierarchy and non-exclusive of the saliency features of any lower feature clusters in the hierarchy. A representative image of each group is designated from respective image records based on: the respective saliency feature of the highest cluster when the highest cluster is a feature cluster and independent of the saliency features when the highest cluster is the remainder cluster.

  • Patent number: 7366994
    Abstract: A method for organizing visual digital objects into a histogram timeline having a first axis with a timeline representing a range of time organized into separate time periods and a second axis orthogonal to the timeline axis representing a number of digital multimedia objects corresponding to portions of the histogram timeline. Each time period is associated with a graphical metaphor extending from the first axis in a direction along the second axis to an extent that indicates a relative number of visual digital objects associated with the time periods. Each said graphical metaphor comprises event icons which group the visual digital objects associated with the selected time period according to events. The icons are proportionately sized to indicate the number of visual digital objects in the group relative to the total number of visual digital objects associated with the selected time period.

  • Publication number: 20080085032
    Abstract: In a computer-mediated method and a system for supplying image records from a collection, an output request is received from a user. An output is generated responsive to the request by locating a set of image records in the collection corresponding to the request, determining one or more constraints on the output, ascertaining a respective value index of each of the image records in the set, calculating a statistical measure of the value indexes of the set, reducing in number the image records in the set responsive to the constraints while optimizing the statistical measure to provide a reduced set of image records, and providing the output using the reduced set of image records.

  • Publication number: 20080085055
    Abstract: In a method and system for providing access to a collection of records via a user interface, a plurality of different partitions of the collection are determined. Each partition is based on a different parameter. Each partition has two or more clusters having different values of the respective parameter. Weights are assigned to each of the clusters relative to all of the other clusters of all of the partitions. The clusters are rank ordered by weight to provide a single ranking. The user interface is equipped with controls that give user-selected direct access to each of the clusters of a leading portion of the ranking.

  • Publication number: 20080085053
    Abstract: An image-record subject is identified for a plurality of image records in an image collection. Then, a sampling change-metric related to a changing characteristic of the image-record subject is identified, and sampling of at least a portion of the image collection occurs at least according to the sampling change-metric to obtain one or more image records for the subset. Information pertaining to results of the sampling step is stored in a computer-accessible memory system.

  • Patent number: 7340676
    Abstract: A system and method for automatic creation of digital image albums. A Page Creator Module utilizes a genetic engine and a layout evaluation module. The genetic engine evolves a group of images to a plurality of album pages, based on certain layout criteria. The evaluation module calculates layout criteria and compares them with user preferences. When an acceptable image/page layout has been generated, the image/page assignments are transferred to an Image Placement Module. The Image Placement Module utilizes a second genetic engine, which evolves various criteria to generate page layouts genetic structures. These structures define the location, scale, and rotation of images placed on a given page. A layout evaluation module calculates and compares these layouts with certain other preferences and page requirements. When a suitable layout has been generated, a final album output is generated, which may be displayed, printed, or otherwise transferred for subsequent utilization.
