Video processing for enabling sports highlights generation
One or more highlights of a video stream may be identified. The highlights may be segments of a video stream, such as a broadcast of a sporting event, that are of particular interest to one or more users. According to one method, at least a portion of the video stream may be stored. The portion of the video stream may be compared with templates of a template database to identify the one or more highlights. Each highlight may be a subset of the video stream that is deemed likely to match the one or more templates. The highlights, an identifier that identifies each of the highlights within the video stream, and/or metadata pertaining particularly to the one or more highlights may be stored to facilitate playback of the highlights for the users.
1. A method for extracting one or more highlights from video stream, the method comprising:
determining, by a computing system, that a subset of a video stream is a highlight by:
detecting, by the computing system, a leading logo and recording a first transition time corresponding to the leading logo, and
detecting, by the computing system; a trailing logo and recording a second transition time corresponding to the trailing logo;
based on the determining, extracting, by the computing system, the subset of the video stream in between the first transition time and the second transition time from the video stream;
determining, by the computing system, whether a current frame count of the video stream exceeds a video length of the video stream; and
in response to determining that the current frame count exceeds the video length:
storing, by the computing system, a plurality of transition times for a plurality of highlights including the first transition time and the second transition time for the highlight.
2. The method of claim 1 , wherein detecting the leading logo comprises:
comparing, by the computing system, a first portion of the video stream with a plurality of logo templates stored in a template database.
3. The method of claim 2 , wherein the detecting the trailing logo comprises:
comparing, by the computing system, a second portion of the video portion with the plurality of logo templates.
4. The method of claim 3 , wherein the plurality of logo templates comprise at least one of: a network logo associated with a television network, a network logo associated with a cable network, a network logo associated with a broadcast network, or a team logo associated with a sports team.
5. The method of claim 3 , wherein each of comparing the first portion of the video stream and the second portion of the video stream with the plurality of logo templates comprises:
using, by the computing system, at least one of a boundary detection technique or peak signal-to-noise ration (PSNR) computation.
6. The method of claim 1 , wherein the leading logo and the trailing logo are associated with a replay sequence in the video stream.
7. The method of claim 1 , further comprising:
causing, by the computing system, an output device to output the video stream concurrently with the extraction of the one or more highlights.
8. A system comprising:
a non-transitory storage medium storing computer program instructions;
a processor configured to execute the computer program instructions to cause operations comprising:
determining that a subset of a video stream is a highlight by:
detecting a leading logo and recording a first transition time corresponding to the leading logo, and
detecting a trailing logo and recording a second transition time corresponding to the trailing logo;
based on the determining, extracting the subset of the video stream in between the first transition time and the second transition time from the video stream;
determining whether a current frame count of the video stream exceeds a video length of the video stream; and
in response to determining that the current frame count exceeds the video length:
storing a plurality of transition times for a plurality of highlights including the first transition time and the second transition time for the highlight.
9. The system of claim 8 , wherein detecting the leading logo comprises:
comparing a first portion of the video stream with a plurality of logo templates stored in a template database.
10. The system of claim 9 , wherein the detecting the trailing logo comprises:
comparing a second portion of the video portion with the plurality of logo templates.
11. The system of claim 10 , wherein the plurality of logo templates comprise at least one of: a network logo associated with a television network, a network logo associated with a cable network, a network logo associated with a broadcast network, or a team logo associated with a sports team.
12. The system of claim 10 , wherein each of comparing the first portion of the video stream and the second portion of the video stream with the plurality of logo templates comprises:
using at least one of a boundary detection technique or peak signal-to-noise ration (PSNR) computation.
13. The system of claim 8 , wherein the leading logo and the trailing logo are associated with a replay sequence in the video stream.
14. The system of claim 8 , wherein the operations further comprise:
causing an output device to output the video stream concurrently with the determining the highlight.
15. A non-transitory computer readable medium storing computer program instructions, which when executed by a processor cause operations comprising:
determining that a subset of a video stream is a highlight by:
detecting a leading logo and recording a first transition time corresponding to the leading logo, and
detecting a trailing logo and recording a second transition time corresponding to the trailing logo;
based on the determining, extracting the subset of the video stream in between the first transition time and the second transition time from the video stream;
determining whether a current frame count of the video stream exceeds a video length of the video stream; and
in response to determining that the current frame count exceeds the video length:
storing a plurality of transition times for a plurality of highlights including the first transition time and the second transition time for the highlight.
16. The non-transitory computer readable medium of claim 15 , wherein detecting the leading logo comprises:
comparing a first portion of the video stream with a plurality of logo templates stored in a template database.
17. The non-transitory computer readable medium of claim 16 , wherein the detecting the trailing logo comprises:
comparing a second portion of the video portion with the plurality of logo templates.
18. The non-transitory computer readable medium of claim 17 , wherein the plurality of logo templates comprise at least one of: a network logo associated with a television network, a network logo associated with a cable network, a network logo associated with a broadcast network, or a team logo associated with a sports team.
19. The non-transitory computer readable medium of claim 17 , wherein each of comparing the first portion of the video stream and the second portion of the video stream with the plurality of logo templates comprises:
using at least one of a boundary detection technique or peak signal-to-noise ration (PSNR) computation.
20. The non-transitory computer readable medium of claim 15 , wherein the leading logo and the trailing logo are associated with a replay sequence in the video stream.
