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.

Additional records are combined into a database of earlier-entered records clustered into existing events. A common chronology of a set of the existing events in the database and the additional records is determined based upon respective date-times of origination. Relative proportions of the earlier-entered and additional records in the database are ascertained. The following are identified in the chronology: existing events immediately preceding, concurrent with, and immediately succeeding additional records. When the relative proportions are beyond a predetermined reuse threshold, all of the records of the set and the additional records are reclustered into new events independent of the existing events. When the relative proportions are within the predetermined reuse threshold, only the identified records are reclustered with the additional records.

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.

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.

A method of grouping images captured in a common location, including receiving a collection of images; classifying the images into a set of events, where each image in the collection belongs to no more than one event; analyzing background region(s) of images from each event to determine one or more features that represent the event; and comparing features from at least two events to determine which events occurred in a common location.

A method of identifying a particular person in a digital image collection, wherein at least one of the images in the digital image collection contains more than one person, includes providing at least one first label for a first image in the digital image collection containing a particular person and at least one other person; wherein the first label identifies the particular person and a second label for a second image in the digital image collection that identifies the particular person; using the first and second labels to identify the particular person; determining features related to the particular person from the first image or second image or both; and using such particular features to identify another image in the digital image collection believed to contain the particular person.

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.

A method for generating customized photo album pages for a collection of digital images comprises the steps of: (a) obtaining a plurality of digital images; (b) automatically grouping the images into one or more image sets based on at least one of grouping by events and grouping by people present in the images; (c) automatically profiling the images within each image set according to image content, thereby relating a particular image set to one or more design themes; (d) providing a database of design elements that may be used to generate customized photo album pages; (e) utilizing the design themes generated by the profiling step to automatically suggest one or more design elements from the database of design elements; and (f) automatically generating a customized photo album page layout for each image set by applying one or more of the suggested design elements to the page layout.

A method for structuring video by probabilistic merging of video segments includes the steps of obtaining a plurality of frames of unstructured video; generating video segments from the unstructured video by detecting shot boundaries based on color dissimilarity between consecutive frames; extracting a feature set by processing pairs of segments for visual dissimilarity and their temporal relationship, thereby generating an inter-segment visual dissimilarity feature and an inter-segment temporal relationship feature; and merging video segments with a merging criterion that applies a probabilistic analysis to the feature set, thereby generating a merging sequence representing the video structure. The probabilistic analysis follows a Bayesian formulation and the merging sequence is represented in a hierarchical tree structure.
摘要:
A method for associating event times or time periods with digital images in a collection for determining if a digital image is of interest, includes storing a collection of digital images each having an associated capture time; comparing the associated capture time in the collection with a special event time to determine if a digital image in the collection is of interest, wherein the comparing step includes calculation of a special event time associated with a special event based on the calendar time associated with the special event and using such information to perform the comparison step; and associating digital images of interest with the special event.
