As shown in figure 1, the embodiment of the present invention provides a kind of data transmission method, it is applied in electronic equipment, the method
Process can be described as follows.
S11：Obtain first video image corresponding with current video communication of the first electronic equipment collection；
S12：First video image is compared with initial video image, determines that the display that the first video image includes is right
Object is shown with the presence or absence of the initial display object included with initial video image is had differences at least one as in；Wherein,
Initial video image is the image gathered before the first video image, and which includes the corresponding video image of current video communication
The image of background parts image, at least one display object be in the first video image location with initial video figure
The display object that location is differed as in；
S13：At least one display corresponding destination image data of object is sent to the be connected with the first electronic equipment
Two electronic equipments, so as to the second electronic equipment show generated and the first video figure based on destination image data and a upper display image
As corresponding display image.
In the embodiment of the present invention, the first electronic equipment can be in video communication state, then by obtaining the first electronics
First video image of equipment currently collection, and then the first video image can be compared with initial video image, so as to
At least one display object that interface is had differences in determining the first video image, at least one display object can be motion
Object, therefore its in the first video image location the location in initial video image is differed with which, this
When, extract at least one of first video image and show the corresponding destination image data of object, and the part partial data sends
To the second electronic equipment, to be based on destination image data and the generation of a upper display image and described first by the second electronic equipment
The corresponding display image of video image, therefore during video, whole image need not be transmitted, it is only necessary to by the video figure of current collection
As the destination image data of the display object having differences with previous frame video image is transferred to the second electronic equipment, so as to
Code check is reduced, bandwidth is saved, restriction of the bandwidth to data transfer is reduced, communication quality is improved.
Optionally, the first video image can be the image of the first electronic equipment Real-time Collection in video communication,
The video image of each collection can be to there is a corresponding collection moment, and such as the first video image corresponding collection moment can be with
It it was the first moment, the second video image gathered after the first video image can correspond to second moment, etc..First regards
A multiple display object can be included in frequency image, the display object can be Background object, user object etc., its
Middle Background object may refer to corresponding Background part during video image acquisition, if for example user 1 enters in room
Row net cast, and lean against wall, then, it is corresponding in the video image of collection to show that object is user 1, corresponding background
Figure part is corresponding wall part in video image.
Initial video image can be located at the video image before the first video image in gatherer process, i.e., when first
The video image of the previous moment collection at quarter, which can include the background parts image of the corresponding video image of current video communication
Image.For example, initial video image can be user when net cast is carried out using video recording equipment, by photographic head gather
First two field picture can be initial video image, then may include corresponding user and Background in first two field picture, for example
Background is studio, and user can be host and welcome guest etc..
Therefore, after the first video image that the first electronic equipment is currently gathered is obtained, which can be set with the first electronics
The standby initial video image in previous moment collection is compared, so that it is determined that relative to initial video figure in the first video image
As at least one display object having differences.
Optionally, when S12 is carried out, its process can include：First video image is carried on the back with initial video image
Scape difference processing, obtains the absolute error average of the present image process block of first video image；Wherein, the absolute mistake
Difference average is the exhausted of the pixel value difference between the present image process block and corresponding image block in the process video image
To average；If it is determined that the absolute error average is more than predetermined threshold value, determines that the present image process block is corresponding and show right
As at least one display object for having differences with initial display object in the initial video image；Otherwise, it determines described
Present image process block is corresponding to show that object is consistent with corresponding initial display object.
As a rule, in video communication, the position of harvester is typically more fixed, multiple videos of its collection
In image, corresponding Background part will not generally change.Therefore during Real-time Collection, by the first of current collection is regarded
Frequency image carries out background difference processing with previous frame video image (i.e. initial video image), just can determine that the first video image
Relative to the part that initial video image has differences, that is, detect during video the location in the first video image
With the moving object that the location in initial video image is differed and corresponding region, for example, carry out shift in position or limb
The user of body language change.
Background subtraction be using the difference of present image and background image detecting a kind of technology of moving region, its
The average as background image of a width or a few width images in background can be chosen, then later sequence image present frame and
Background image subtraction, carries out background cancellation.
When in processing procedure carrying out being subtracted each other by image, it is typically required current video image (i.e. the first video
Image) multiple images process block is divided into, for example can be divided according to pixel, such as 8*8 or 16*16 etc., accordingly, just
Beginning video image will also be the block for being divided into respective numbers according to same way, and will be corresponded in two video images respectively one by one
Image processing block in pixel value subtract each other, and then obtain currently processed piece of absolute error average.And then determine absolute error
Whether average is more than predetermined threshold value, and such as 1.5 or other numerical value, in actual applications, those skilled in the art can be based on real
Border demand is configured to predetermined threshold value, and the embodiment of the present invention is not specifically limited to this.
If it is determined that whether absolute error average is more than predetermined threshold value, then show the corresponding display object of present image process block
Initial display object in process block corresponding with initial video image has differences, now can be in present image process block
Show object as determine have differences at least one show object.Otherwise, it is believed that the initial position for showing object
Or form etc. does not change.Then in actual applications, by the absolute error average to each image processing block in video image
Calculating, you can it is determined that whether have moving object in monitored scene (i.e. video collection area), so as to obtain moving target, example
Such as at least one display object.
For example, image as shown in Figure 2 A is the first moment (such as 12:01:22) previous moment (such as 12:01:20)
The initial video image of collection, the image shown in Fig. 2 B are the first video image of the first moment collection, wherein, the first video figure
As including Background, user a and user b, positions 1 of the user a in image, user b are in position 2, initial video figure
As including Background, user a and user b, position 3 is in for a in position 1, user b, position 2 and position 3 differ,
Then can be determining the motion that has differences (moved during video) relative to initial video image in the first video image
Object is as user b, therefore the image having differences partly is not user b corresponding image portions in the first video image
Point.
Further, after at least one display object is determined, which can be extracted from the first video image, and
This parts of images is transferred to into corresponding second electronic equipment, the process can be：Institute is extracted from first video image
The corresponding target part image of at least one display object is stated, and then the corresponding destination image data of destination object image is carried out
Coding, and the destination image data after coding is sent to into the second electronic equipment.
Wherein, the second electronic equipment can set up to be connected and the equipment with display unit with the first electronic equipment, example
As which can be independent display, or, or there is collecting unit (for example to image with the first electronic equipment identical
Head, mike etc.) and display unit (such as touch-control/non-touch-control display screen) equipment, such as notebook, PAD, video recording equipment etc.
Deng the embodiment of the present invention is not specifically limited to this.
Optionally, when at least one display object corresponding target part image in the first video image is extracted, also
Target part image section corresponding pixel coordinate in the first video image can be recorded, and then again to destination object image
Destination image data is encoded, and the destination image data after coding is sent to the second electronic equipment.
Wherein, when encoding to destination image data, it may be determined that destination object image is in the first video image
Corresponding class parameter, the class parameter can be used for characterizing the corresponding concerned degree for showing object of destination object image,
For example can the grade of the corresponding image of conversation object more important in video communication (such as video conference) be arranged higher, such as will
Picture part in video pictures corresponding to speaker (such as president) is set to highest ranking parameter, such as one-level, or even may be used also
To arrange other levels, the people of conference participation corresponding image section is set to into two grades such as, service personal is set to three-level, etc.
Deng.
And then available bandwidth and class parameter can be based on, the coding parameter of destination image data, the coding parameter are set
Can indicate that destination image data code check corresponding after encoding, i.e., it is related to the transmission code rate of the data after coding.Optionally,
In video image, corresponding image section class parameter is higher, then show which is crucial personage or object, needs to ensure which
Video instructions, you can ensure its fluency with by arranging coding parameter.
In the embodiment of the present invention, coding parameter can be quantization parameter, such as quantizing bit number, and quantization parameter can be used in
Phenogram is as corresponding precision.In actual applications, the class parameter of the corresponding destination object image of destination image data is bigger,
The quantization parameter of relative set can be bigger, and the corresponding precision of destination object image for being characterized is also higher, corresponding number
Also bigger according to measuring, the code check produced after coding is also bigger, but no more than the corresponding maximal rate of current available bandwidth.Accordingly
, the class parameter of the corresponding destination object image of destination image data is lower, and the quantization parameter of relative set can be less, institute
The corresponding precision of destination object image for characterizing is also less, and the code check produced after coding is also less, to bandwidth requirement more
It is low, it is not more than current available bandwidth.
Wherein, the data bits of unit interval transmission when code check is exactly data transfer, general unit is Kbps i.e. thousand
Bits per second, Kbps refer to network speed, that is, (K represents kilobit, what Kb was represented to transmit the information of how many kilobits each second
It is how many thousand positions), in order to the transmission speed in the network that intuitively seems is very fast, general company all uses kb (kilobit) to carry out table
Show, 1KB/S=8Kbps.On ADSL (Asymmetric Digital Subscriber Line, ADSL)
Network speed during net is 512Kbps, if translated into byte, is exactly 512/8=64KB/S (i.e. 64 kilobytes are per second).Generally come
Say, if the broadband of 1M, can only see the video less than 125Kbps on the net, the video more than 125Kbps can only wait video
Buffering smoothly could be watched.
In the embodiment of the present invention, due to transmit in video transmitting procedure be merely in the presence of difference at least one display it is right
As corresponding destination object image, compared with needing in prior art, the code check for transmitting whole video image is much lower.Example
Such as, if the use of the bandwidth for transmission data volume of 1M is the video image of 1.5M, corresponding code check is probably 125kbps, and is passed through
The video image and background image portion are carried out into background difference processing, it is determined that needing the image section having differences of transmission
Data volume can be solely 250kb, then code check of its corresponding transmission can be 25kbps, or other numerical value, as a rule based on setting
Maximum code stream of the corresponding code check of quantization parameter put not over bandwidth, such as 125kbps.
Accordingly, the second electronic equipment can enter to which after the destination image data for receiving the transmission of the first electronic equipment
Row decoding, and then the upper display picture that decoded destination object object is shown with which, the display picture are and first
The corresponding display picture of video image.
Therefore, in the embodiment of the present invention, in video conference process, can be based on the importance of video content and current
Bandwidth, is guaranteeing meeting quality (including the video quality of the corresponding image such as key person or critical object, and video harmony
The fluency of sound) on the premise of, realize the adjust automatically to the code check of current video, i.e., based on a determination that the target having differences
The difference of object images, the code check after its correspondence is encoded also can be different, so as to based on the corresponding grade ginseng in the part having differences
Number and current available bandwidth can dynamically adjust code check, improve the motility of transmission.
Optionally, in video communication, the first electronic equipment can also receive the video from the second electronic equipment
Data, and then corresponding picture is shown by itself obtaining display unit.
The process can include：The second packet from the second electronic equipment is received, the second packet includes second
The Moving Objects image having differences between second video image and default video image of its collection that electronic equipment determines, and
Pixel coordinate of the Moving Objects image in current video image.
Further, it may be determined that in the first electronic equipment previous moment of the display unit at current time show it is electric with second
Corresponding first display picture of the corresponding video image of sub- equipment, first display picture can be corresponding to default video image,
That is the display picture that previous moment shows in the first electronic equipment is corresponding to the default video image of the second electronic equipment of opposite end.
In actual applications, the default video image can be that the second electronic equipment is gathering the current of the second video image
The video image gathered by the previous moment at moment, from visual effect for, the first electronic equipment show first display picture
Face can be identical with default video image.
In the same manner, the second electronic equipment can also determine the Moving Objects figure having differences according to above-mentioned data transmission method
Picture, and the first electronic equipment after being encoded, is sent to, the first electronic equipment, can be right to moving after the second packet is obtained
As image is decoded, obtain Moving Objects image and corresponding pixel coordinate, and determine in the first display image with move it is right
As the corresponding display object images of image.
For example, if Moving Objects object for user b the corresponding image of head (the i.e. head figure of current time user b
Picture), it is determined that the first display image in display object images be user b head for image, that is, go up a moment
The head image of user b.
Further, the first display image can be combined with Moving Objects image, generates what current time correspondence showed
Second display image, then the second display image be based on the second electronic equipment partial data generate with the second video
The corresponding display image of image.
Specifically, when the second display image is generated, can show that object images turn by corresponding in the first display image
Background part is changed to, and then pixel coordinate can be based on, by Moving Objects image update to the first display image, you can generate
The second display image corresponding with current time.
Below by the application scenarios for illustrating data transmission method in the embodiment of the present invention.
