Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
A~Figure 1B referring to Fig.1 can explicitly understand the concept of so-called video labeling.It, can in video labeling technology
Each user is set to enjoy marking Function；This is just easy to occur, and a large amount of different users are labelled with same or similar area
Domain, and same or different related information may be associated with for the region.As shown in Figure 1 C, three have the wire frame of overlapping for difference
The region that user is marked, when user instruction rests in overlapping region, the related information emerged out may be any mark
The related information of note.When a large number of users is labeled, so that some region is there are when dozens of even up to a hundred marks, association is believed
Cease display confusion as one can imagine.This is also urgent problem to be solved in the prior art.
The present invention solves the above technical problem for by merging the video labeling in same or similar region.Specifically, this
Invention will provide a kind of video labeling method, the specific embodiment shown in Figure 2 for the method for the invention:
Step 201, server end setting mark interface.
Server setting mark interface, and the mark interface is provided to playback terminal, this means that playback terminal
Provide the correlation function that video is labeled；Playback terminal can submit relevant markup information with life by the mark interface
Produce mark.
Step 202, when video playing terminal is in playing process, generate markup information for video image and by described
It marks interface to submit to server, then server receives the markup information, and extracts corresponding view according to the markup information
Frequency section.
When the user of playback terminal is by mark interface, for the fixed area progress video labeling in particular video frequency image
When, the corresponding information of the image-region that will be identified by, and this partial information will be used as markup information.
The markup information includes video number, mark moment and tab area.The video number is to be marked video
ID；The mark moment is when being marked image display, to be marked the play time of video；The tab area is video mark
Note covering is marked the coordinate range of video image, specifically can be the coordinate range of video labeling covering, is also similar to figure
Wire frame in 1B or Fig. 1 C.
User sets markup information by playback terminal and markup information is uploaded to video server；Video server
Just it specifies the concrete form of mark, video labeling is actually generated according to the markup information in order to subsequent.In addition, the mark
Infuse in information to add with the corresponding related information of the mark as needed.
In the present embodiment, after video server has received the markup information, according to the markup information find by
The video of mark, and corresponding video section is extracted from being marked in video.The video section is by marking in video
It infuses within the scope of moment or even front and back some time at mark moment composed by all video frames, all videos in video section
Frame has identical or similar image.
Such as the consecutive image under Same Scene camera lens, that is, it is divided within same video section.Assuming that certain video
The image of 0 "~20 " displays is similar to " girl's face " shown in figure 1A；Camera lens switches over immediately, the figure of 20 "~38 " displays
As being similar to shown in Fig. 1 D " doggie ".So video 0 "~20 " are a video section, and 20 "~38 " be another video
Section.
It is appreciated that if only the frame or a few frame images at the mark moment are marked, then the video labeling is deposited
Time will be excessively of short duration, can not be used by a user.And in video section, what same image-region was often shown is always
Identity element.So in general, video labeling should not be merely present in the mark moment, but should be within the video section time
It is existing always.
Step 203, server judge in the video section, if reach there are registration with the markup information and be overlapped
The markup information is then merged into the video labeling by the video labeling of threshold value if it exists；If it does not exist then according to
Markup information generates video labeling.
To avoid the display of information caused by repeat mark chaotic in the present embodiment, thus extract the video section it
Afterwards, judge within the video section, if be already present on the mark higher video labeling of area coincidence degree in markup information.Such as
Fruit exists, and just no longer establishes new video labeling for the markup information, but is incorporated into already present video labeling and works as
In, retain original standardized tab area.Thus avoid duplicate mark.In same or similar region if there is no
Duplicate video labeling would not naturally also lead to the problem of related information display confusion.
If instead there is no the higher marks of registration within the section, then the markup information submitted according to this is raw
The mark of Cheng Xin.
As seen through the above technical solutions, beneficial effect existing for the present embodiment is: by merging same or similar region
Interior video labeling avoids and establishes duplicate video labeling, so that the display of the related information of video labeling has become clear
Sequence.
It is another specific embodiment of the method for the invention referring to shown in Fig. 3.It will be in aforementioned implementation in the present embodiment
On the basis of example, it is described in more detail and openly.Method described in the present embodiment the following steps are included:
Video is divided into several sections according to picture material, and is that the section establishes view according to play time by step 301
Frequency indexes.
In the present embodiment, video server can be previously-completed the division of video section, and established and regarded according to dividing condition
Frequency indexes.
For example, the video for being 00001 to video number, carries out the division of video section, which is 1 ', wherein
0 "~15 " be first video section, 15 "~35 " be second video section, 35 "~53 " be third video section, 53 "
~60 " be the 4th video section.One video index such as table 1 is established to this division result:
| Session name | Time range |
| Section 1 | 0 "~15 " |
| Section 2 | 15 "~35 " |
| Section 3 | 35 "~53 " |
| Section 4 | 53 "~60 " |
Table 1
Step 302, setting mark interface, are believed by mark set by the mark interface video playing terminal
Breath, the markup information include video number, mark moment and tab area.
The number of video described in the present embodiment is 00001, and the mark moment is 26 ", and the tab area is the seat in image
It marks data x ∈ (225,324)；y∈(105,188).
Step 303 searches corresponding video index by video number, and according to the mark moment to the view
Frequency search index obtains mark moment corresponding video section.
It is 00001 according to video number, the mark moment is 26 ", can extract the section 2 in table 1.
It should also be noted that, illustrating the view when not finding corresponding video index by video number
Frequency numbers corresponding video and establishes video index not yet.Then in this case, video server is that video number corresponds to
Video establish video index, and obtain established video index, then corresponding area is extracted from the video index established
Section.
Step 304, default coincidence threshold value, and obtain already present video labeling in the video section；
After extracting the section 2 in table 1, already existing video labeling in the section is obtained.The already present view
Frequency marking note, often has already passed through merging, and the video labeling that range has been standardized.It is got in the present embodiment, area
There are a video labeling in section 2, coordinate data is (220,320) x ∈；y∈(100,180).Additionally need setting one
It is overlapped threshold value, to judge the registration of the tab area in markup information Yu existing mark；Registration threshold value in the present embodiment
It is essentially coordinate data difference, specially 10.
Step 305, the coordinate data for calculating the tab area, the difference with the coordinate data of video labeling in video section
Value.
If step 306, the difference are not more than the coincidence threshold value, then it is assumed that the tab area and the video labeling
Registration reach coincidence threshold value.
By can be calculated, the coordinate data difference of tab area and video labeling is as follows: △ x (5,4), △ y (5,
8)；The above difference is not more than registration threshold value 10, it is believed that its registration has reached registration threshold value.
Step 307, if it exists registration reach the video labeling for being overlapped threshold value with the markup information, then by the mark
Information is merged into the video labeling.
In the present embodiment, the registration has reached registration threshold value, just no longer establishes video mark for the markup information
Note, but be merged into already present video labeling, the range retention criteria range x ∈ (220,320) of mark；y∈
(100,180), 2 duration 15 "~35 " of time, that is, section existing for standard；If further wrapped in the markup information
Related information is included, then the related information is associated on the video labeling.
If reaching the video for being overlapped threshold value with the markup information there is no registration in step 308, the video section
Mark then generates a video labeling according to the markup information.
Preferably, the video labeling of registration threshold value is reached if there is no registration, then is illustrated within tab area still
There is no video labelings, then newly establish a video labeling according to the markup information.
As seen through the above technical solutions, beneficial effect existing for the present embodiment is: in the present embodiment, the method is whole
Technical solution is more complete, open more abundant.
It is the specific embodiment of system of the present invention referring to shown in Fig. 4.The system is for realizing in previous embodiment
