摘要： In an image classification method, a plurality of grouping values are received. The grouping values each have an associated image. An average of the grouping values is calculated. A variance metric of the grouping values, relative to the average is computed. A grouping threshold is determined from the variance metric. Grouping values beyond the grouping threshold are identified as group boundaries. The images are assigned to a plurality of groups based upon the group boundaries.

摘要： 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.

摘要： 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.

摘要： A method for automatically classifying images into events, the method includes the steps of: receiving a plurality of images having either or both date and/or time of image capture; determining one or more largest time differences of the plurality of images based on clustering of the images; and separating the plurality of images into the events based on having one or more boundaries between events which one or more boundaries correspond to the one or more largest time differences.

摘要： Generating a tag layout from a set of tags and an ordering of the set of tags, wherein each tag includes a text label and a size for the text label, is disclosed. The method further includes receiving at least one closed shape corresponding to a space for the tag layout. A processor computes a scale factor for at least one of the closed shape or the size of the text labels in the set of tags to generate the tag layout of the set of tags within the closed shape such that all the tags in the set of tags fit within the closed shape and the tags are placed in the space based at least upon the ordering of the tags in the set of tags.
