First Claim
Patent Images
1. A computer-implemented method for identifying sports highlights within videos, the method comprising:
- receiving, using a hardware processor, at least a portion of a video content item of a sporting event;
extracting, using the hardware processor, from the portion of the video content item, a plurality of features associated with one or more frames of the portion of the video content item;
determining, using the hardware processor, whether a feature of the plurality of features matches a previously identified event of a plurality of previously identified events, wherein each of the plurality of previously identified events is an identifiable pattern of features within video content items;
in response to determining that the feature matches the previously identified event, determining, using the hardware processor, whether the portion of the video content item contains a sports highlight; and
in response to determining that the portion of the video content item contains the sports highlight, designating, using the hardware processor, the portion of the video content item as containing the sports highlight.

Abstract
A highlight learning technique is provided to detect and identify highlights in sports videos. A set of event models are calculated from low-level frame information of the sports videos to identify recurring events within the videos. The event models are used to characterize videos by detecting events within the videos and using the detected events to generate an event vector. The event vector is used to train a classifier to identify the videos as highlight or non-highlight.

8. A computer-implemented system for identifying sports highlights within videos, the system comprising:
-
a memory; and a hardware processor that, when executing computer executable instructions stored in the memory, is configured to; receive at least a portion of a video content item of a sporting event; extract, from the portion of the video content item, a plurality of features associated with one or more frames of the portion of the video content item, determine whether a feature of the plurality of features matches a previously identified event of a plurality of previously identified events, wherein each of the plurality of previously identified events is an identifiable pattern of features within video content items; in response to determining that the feature matches the previously identified event, determine whether the portion of the video content item contains a sports highlight; and in response to determining that the portion of the video content item contains the sports highlight, designate the portion of the video content item as containing the sports highlight. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for identifying sports highlights within videos, the method comprising:
-
receiving at least a portion of a video content item of a sporting event; extracting, from the portion of the video content item, a plurality of features associated with one or more frames of the portion of the video content item; determining whether a feature of the plurality of features matches a previously identified event of a plurality of previously identified events, wherein each of the plurality of previously identified events is an identifiable pattern of features within video content items; in response to determining that the feature matches the previously identified event, determining whether the portion of the video content item contains a sports highlight; and in response to determining that the portion of the video content item contains the sports highlight, designating the portion of the video content item as containing the sports highlight. - View Dependent Claims (16, 17, 18, 19, 20, 21)
