Method and system for segmenting and identifying events in images using spoken annotations
First Claim
1. A method for automatically organizing digitized photographic images into events based on spoken annotations, where the events are useful in organizing photographic albums, said method comprising the steps of:
- providing natural-language text based on spoken annotations corresponding to a plurality of frames of photographic images;
extracting predetermined information from the natural-language text that characterizes the annotations of the images;
segmenting the images into events by examining each annotation for the presence of certain categories of information which are indicative of a boundary between events; and
identifying each event by assembling the categories of information into event descriptions.

Abstract
A method for automatically organizing digitized photographic images into events based on spoken annotations comprises the steps of: providing natural-language text based on spoken annotations corresponding to at least some of the photographic images; extracting predetermined information from the natural-language text that characterizes the annotations of the images; segmenting the images into events by examining each annotation for the presence of certain categories of information which are indicative of a boundary between events; and identifying each event by assembling the categories of information into event descriptions. The invention further comprises the step of summarizing each event by selecting and arranging the event descriptions in a suitable manner, such as in a photographic album.

14. In a method wherein image frames are segmented into events by examining annotation data for the presence of certain categories of information which are indicative of a boundary between events, the improvement wherein the method of segmentation comprises the steps of:
-
assigning a strength value for the certain categories of information which are indicative of a boundary between events;
computing the evidence in favor of and against an event break with regard to a current frame by summing the strength values from the certain categories of information present for the current frame relative to a preceding frame already allocated to a current event; and
allocating the frame to a new event when the summarized strength values in favor of an event break exceed a predetermined threshold, otherwise allocating the frame to the current event. - View Dependent Claims (15, 16, 17)

18. In a method for automatically organizing digitized consumer images into events based on natural-language text corresponding to spoken annotations, wherein predetermined information characterizing the annotations of the images is automatically extracted from the natural-language text by use of a gazetteer, the improvement wherein the gazetteer comprises a collection of indices including commonly-used proper names, place names including typical tourist spots and celebration places, currency names, function or stop words, irregular verb forms, regular verbs, college and university names and typical events.

19. A computer program product for automatically organizing digitized photographic images into events based on spoken annotations, where the events are useful in organizing photographic albums, said computer program product comprising a computer readable storage medium having a computer program stored thereon for performing the steps of:
-
providing natural-language text based on spoken annotations corresponding to at least some of the photographic images;
extracting predetermined information from the natural-language text that characterizes the annotations of the images;
segmenting the images into events by examining each annotation for the presence of certain categories of information which are indicative of a boundary between events; and
identifying each event by assembling the categories of information into event descriptions. - View Dependent Claims (20)
