Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As it is shown in figure 1, the processing method embodiment flow chart of the live video of embodiment of the present invention offer,
Including:
Step 101, determine in the picture frame of live video corresponding with the specific part of net cast person
Pixel；
Step 102, the pixel that the specific part of described net cast person is corresponding is carried out by predetermined manner
Process, the described picture frame after being processed；
Step 103, to process after described picture frame play out.
In embodiments of the present invention, the specific part of target site net cast person refers to live video
In pending position, can be such as the whole people of video main broadcaster, or the spy of video main broadcaster's health
Determine position (such as eyes, nose, hair, face etc.), or other in live video is specific
Position (all background images as in addition to video main broadcaster), specific to target site net cast person
Position carries out the mode processed, for example, it is assumed that target site can be video main broadcaster, then carries out U.S. face
Process, it is assumed that target site is all background images in addition to video main broadcaster, then can be by waiting filter
Ripple, noise reduction etc. processes, and reaches to beautify the effect of the specific part in video, naturally it is also possible to be other
Processing mode, as increased cartoon effect, increases the brightness etc. of video image, for concrete process side
Formula, the present invention is not specifically limited.
For example, if the specific part of net cast person is the eyes of video main broadcaster, then at this
In bright embodiment, when video is carried out live, it is that the glasses to video main broadcaster carry out U.S. face process all the time,
Other position is not processed, i.e. can realize the requirement according to user, specific part is entered
Row processes, and then meets the specific demand of user.
Below the processing method of live video is specifically described by the embodiment of the present invention.
In above-mentioned steps 101, when doing live video and processing, each two field picture is processed,
Thus when picture frame is processed, it is first determined with net cast person's in the picture frame of live video
The pixel that specific part is corresponding, the specific part of described net cast person is pending position.Such as,
If needing the specific part of net cast person carrying out processing is the eyes of video main broadcaster, first determine
With the pixel corresponding to eyes in picture frame, alternatively, in the described picture frame determining live video with
The pixel that the specific part of net cast person is corresponding, including: right according to default pixel characteristic and position
Should be related to, determine pixel corresponding with the specific part of described net cast person in described picture frame.Optional
Ground, the pixel characteristic in the corresponding relation at described default pixel characteristic and position comprise following part or
Whole: the size that pixel quantity, pixel value size, pixel are constituted.
In the above-mentioned methods, picture corresponding with the specific part of net cast person in picture frame is determined when wanting
During element, it is the corresponding relation according to the pixel characteristic preset with position, determines that net cast person's is specific
Feature corresponding to position, wherein, part that described pixel characteristic refers to have in following features or
Person is whole: the size that pixel quantity, pixel value size, pixel are constituted.For example, with reference to figure
2, the picture frame schematic diagram of live video provided for the embodiment of the present invention, it is assumed that default pixel characteristic with
In the corresponding relation at position: the pixel characteristic that eyes are corresponding is: number of pixels is 10-30, and each pixel is big
Little span is 100～200, and the areal extent that all pixels are constituted is 20～50, then can pass through eye
These pixel characteristic corresponding to eyeball, remove to search a picture of this pixel characteristic concrete in a picture frame
Element set, such as, have found the region 1 in Fig. 2 and region 2 and have above-mentioned pixel characteristic, then will
All pixels in region 1 and all pixels in region 2 are defined as the pixel corresponding to eyes, according to
Same mode, it may be determined that the pixel that nose is corresponding is all pixels in region 3, and face is corresponding
Pixel is all pixels in region 4.Thus based on above method, can find in a picture frame
The pixel that the specific part of net cast person is corresponding.
In above-mentioned steps 102, the pixel corresponding to the specific part of described net cast person is square by presetting
Formula processes, the described picture frame after being processed, and specifically processing mode does not limits, alternatively, and institute
The pixel stating the specific part to described net cast person corresponding is processed by predetermined manner, including: right
The pixel that the specific part of described net cast person is corresponding carries out landscaping treatment according to the default mode of beautifying.
Such as, when to be processed be the positions such as the eyes of video main broadcaster, face, nose time, can be right
Pixel corresponding to these positions carries out landscaping treatment according to default mode, specifically beautifies mode permissible
It is that filtering noise reduction etc. processes, thus reaches to beautify the purpose of the specific part of net cast person.
In above-mentioned steps 103, the described picture frame after processing is played out.
By above-mentioned steps 101～step 103, can realize all the time in every two field picture of live video
The pixel corresponding with the specific part of net cast person processes, thus reaches all the time to live video
In the specific part of net cast person process, such that it is able to meet the demand of user.
Additionally, the specific part of the net cast person in above-mentioned steps 101～step 103, alternatively,
Can be the specific part determining described net cast person according to following manner:
Mode one, input according to user, obtain the specific part of described net cast person
In this approach, can be before live video is processed such as, user be manually entered
Want to carry out the specific part of the net cast person of special handling, as user can input " main broadcaster's eyes ",
" main broadcaster's hair ", " main broadcaster face ", " video background " etc., so that it is determined that need to regard live
Frequency carries out the specific part of the net cast person of special handling.
Mode two, the position selected in the picture frame of live video according to user, determine described video
The specific part of live person
In this approach, such as can by be by user by touch screen or click in the way of, directly
Broadcast and the image of video is selected out a region, position corresponding for this region is defined as net cast person
Specific part, such as user is by the selected eyes that region is video main broadcaster of mouse, the most really
The specific part determining net cast person is main broadcaster's eyes.
