Method and device for determining inter-cut time range in media item
This specification describes techniques for determining an inter-cut time range in a media item. In one example method, a set of candidate segmentation points representing time points in a media item is determined, wherein each candidate segmentation point represents at least one of a time point at which feature media data appears in the media item, or a time point at which feature media data disappears from the media item. Based on the candidate segmentation points, an inter-cut time range is identified. The inter-cut time range is associated with a start point from the candidate segmentation points that satisfies a predetermined start point condition, and the inter-cut time range is associated with an end point from the candidate segmentation points that satisfies a predetermined end point condition. The inter-cut time range represents a time period between the start point and the end point in the media item.
1. A computer-implemented method for determining an inter-cut time range in a media item, comprising:
determining candidate segmentation points representing time points in the media item, wherein each candidate segmentation point represents a start time point at which a feature image displayed in a first video picture produced at a first time during playing the media item is not displayed in a second video picture produced at a second time during playing the media item and a feature sound associated with the feature image is produced when the feature image is not displayed in the second video picture at the second time, and an end time point at which the feature image is displayed in a third video picture produced at a third time during playing the media item after the second time and the feature sound associated with the feature image in the third video picture is not produced at the third time during playing the media item; and
identifying an inter-cut time range based on the candidate segmentation points, the inter-cut time range representing a time period between the start time point from the candidate segmentation points and the end time point from the candidate segmentation points.
2. The computer-implemented method of claim 1 wherein the feature image is located in a predetermined area in the second video picture, and wherein determining the candidate segmentation points comprises:
analyzing at least one of a color ratio or a graphics shape of the predetermined area in the second video picture; and
identifying, as a candidate segmentation point, at least one of a time point at which the feature image appears in the predetermined area at the third time or a time point at which the feature image does not appear in the predetermined area at the second time.
3. The method according to claim 1 , wherein the feature image comprises a scoreboard in a sports game video.
4. The computer-implemented method of claim 1 , wherein the feature sound comprises a sound with at least one of a predetermined volume, tone, or timbre.
5. The computer-implemented method of claim 1 , further comprising, during playing of the media item at a fourth time, using different colors in a progress bar to show an area corresponding to the inter-cut time range and an area corresponding to a non-spot period.
6. The computer-implemented method of claim 1 , further comprising, during playing of the media item at a fourth time, skipping the inter-cut time range.
7. The computer-implemented method of claim 1 , further comprising, during playing of the media item at a fourth time, deleting the inter-cut time range from the media item.
8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
determining candidate segmentation points representing time points in a media item, wherein each candidate segmentation point represents a start time point at which a feature image displayed in a first video picture produced at a first time during playing the media item is not displayed in a second video picture produced at a second time during playing the media item and a feature sound associated with the feature image is produced when the feature image is not displayed in the second video picture at the second time, and an end time point at which the feature image is displayed in a third video picture produced at a third time during playing the media item after the second time and the feature sound associated with the feature image in the third video picture is not produced at the third time during playing the media item; and
identifying an inter-cut time range based on the candidate segmentation points, the inter-cut time range representing a time period between the start time point from the candidate segmentation points and the end time point from the candidate segmentation points.
9. The non-transitory, computer-readable medium of claim 8 , wherein the feature image is located in a predetermined area in the second video picture, and wherein determining the candidate segmentation points comprises:
analyzing at least one of a color ratio or a graphics shape of the predetermined area in the second video picture; and
identifying, as a candidate segmentation point, at least one of a time point at which the feature image appears in the predetermined area at the third time or a time point at which the feature image does not appear in the predetermined area at the second time.
10. The non-transitory, computer-readable medium of claim 8 , wherein the feature image comprises a scoreboard in a sports game video.
11. The non-transitory, computer-readable medium of claim 8 , wherein the feature sound comprises a sound with at least one of a predetermined volume, tone, or timbre.
12. A computer-implemented system, comprising:
one or more computers; and
one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
determining candidate segmentation points representing time points in a media item, wherein each candidate segmentation point represents a start time point at which a feature image displayed in a first video picture produced at a first time during playing the media item is not displayed in a second video picture produced at a second time during playing the media item and a feature sound associated with the feature image is produced when the feature image is not displayed in the second video picture at the second time, and an end time point at which the feature image is displayed in a third video picture produced at a third time during playing the media item after the second time and the feature sound associated with the feature image in the third video picture is not produced at the third time during playing the media item; and
identifying an inter-cut time range based on the candidate segmentation points, the inter-cut time range representing a time period between the start time point from the candidate segmentation points and the end time point from the candidate segmentation points.
