摘要:
A method of classifying a set of semantic concepts on a second multimedia collection based upon adapting a set of semantic concept classifiers and updating concept affinity relations that were developed to classify the set of semantic concepts for a first multimedia collection. The method comprises providing the second multimedia collection from a different domain and a processor automatically classifying the semantic concepts from the second multimedia collection by adapting the semantic concept classifiers and updating the concept affinity relations to the second multimedia collection based upon the local smoothness over the concept affinity relations and the local smoothness over data affinity relations.

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:
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.
摘要:
In methods and systems for classifying capture records, such as images. A collection of capture records is provided. Each capture record has metadata defining a map location. This metadata can be earlier determined from a stream of data transmissions, even if there are gaps in transmission. The provided capture records are clustered into groups based on capture locations. A map, inclusive of the capture locations, is segmented into a plurality of regions based on relative positions of the capture locations associated with each group. The regions are associated with the capture records of respective groups.

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:
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 of identifying a particular background feature in a digital image, and using such feature to identify images in a collection of digital images that are of interest, includes using the digital image for determining one or more background region(s), with the rest of the image region being the non-background region; analyzing the background region(s) to determine one or more features which are suitable for searching the collection; and using the one or more features to search the collection and identifying those digital images in the collection that have the one or more features.
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:
A method for comparing image content of first and second images, the method comprises the steps of extracting a portion of both the first and second images both of which portions are determined to include a main subject area of each image; dividing the main subject area of the images into a plurality of blocks; computing a color histogram for one block in each image; computing a histogram intersection value between the block of the first image and the block of the second image; and determining a first threshold value for the computed histogram intersection value that determines similarity between the block in the first image and the block in the second image.
