Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
In order to solve prior art problem, an embodiment of the present invention provides a kind of video image quality comparative approach and device, with
Suitable for the application in the network platform.
A kind of video image quality comparative approach is provided for the embodiments of the invention first below to be introduced.
When showing applied to terminal referring to Fig. 1, Fig. 1, a kind of stream of video image quality comparative approach of the embodiment of the present invention
Journey schematic diagram, may comprise steps of：
S101 obtains a pair of video frame picture to be compared by the browser of terminal from network side, the pair of to be compared
Video frame picture includes the first picture and second picture；First picture and the second picture are previously uploaded to the clothes
Business device；And first picture is identical with the image content of second picture, respectively from the first video file and the second video file
Middle interception obtains；First video file and second video file be same video content via different coding mode at
Manage the video file obtained；
Wherein, the first video file and the second video file can be same video contents via different coding algorithm process
Obtain two files, can also one be video content unprocessed form, the other is unprocessed form is through certain Optimized Coding Based
Gained after algorithm process.First picture is identical with the image content of second picture, but due to being by distinguishing in different video file
Interception obtains, their image quality is likely to different.By the comparison of the image quality to them, to judge different video text
The quality of the image quality of part, and the quality of different coding mode is judged in turn.
In the embodiment of the present invention, network side can correspond to one or more terminals.For example, carrying out the first picture and second
The terminal of the upload of picture can be identical or different；First picture and second picture are uploaded to after network side, are carried out later
The terminal that picture compares is also entirely possible to be different from transmission terminal on any one picture.
Identical first picture of image content and second picture, possible size simultaneously differ.This is usually because first regards
The video size of frequency file and the second video file is inherently different.In order to more easily carry out the comparison of subsequent pic quality,
The embodiment of the present invention is preferably adjusted dimension of picture by network side, makes the first picture and second picture that are fed back to terminal
Size it is consistent.
Picture request can be sent to network side, picture request includes the pair of to be compared regards by browser
Frequency frame picture needs size so that network side to terminal when feeding back a pair of video frame picture to be compared, a pair for being fed back
The size of video frame to be compared, which meets, described needs size；A pair video to be compared from server feedback is received by browser
Frame picture.
That is, it is preferable that when sending picture request, terminal incidentally has sent required the by browser
The size of one picture and second picture.Network side receives need size after, checking whether the first picture and second picture meet needs
Size is wanted, if met, just directly feeds back picture, if do not met, first size zooms in and out as required by picture, then instead
Present picture.
S102 compares interface, by first picture and the second picture split in the video that the browser provides
User's progress video image quality is displayed for compare.
Compare on interface in the video that the browser provides, the first picture and second picture are compared.Usually,
First picture and second picture are subjected to split and show that the person of comparison that can be more convenient for more meticulously is compared, and is also easier to comment
The image quality for sentencing two pictures is good and bad.
For example, on the image content of video frame, possible there are one facial image, such facial image also tends to be not
The video viewers come more launch the place of attention.Therefore for the video person of comparison, expression, expression in the eyes of face etc.
The expression effect of details is often the contrast points for evaluating picture image quality quality.If two pictures are not carried out split to show, and
It is only simply displayed side by side, then the display location of the human eye on this picture and the human eye on that picture is far apart and unfavorable
In the comparison of the person of comparison.It is therefore necessary to so that the human eye piece piece in two pictures is shown, that is to say, that make the people of a part
Eye display is derived from the first picture, and the human eye of another part shows and is derived from second picture, is obviously more advantageous to judge two in this way
The image quality of picture is good and bad.Certainly, this is merely illustrative the benefit for showing the progress split of two pictures.The particular content of picture
Varied, how to show the first picture and second picture progress split can be there are many method.But what is certain is that with
Certain mode shows two picture splits, can reach the technique effect for making the image quality person of comparison be easier to comparison.Specifically, originally
The realization method of inventive embodiments can be：
The video compare the first display area that the video comparison domain at interface is divided by a removable cut-off rule and
Second display area；
When the cut-off rule is moved to any position, described first is shown in the first display area of video comparison domain
A part for picture shows a part for the second picture so that the first figure in the second display area of video comparison domain
The displayed portion of piece and the displayed portion of second picture complementally form third picture, and make the third picture and institute
It is identical with the second picture image content to state the first picture.
Herein, third picture respectively takes a part to be put together by the first picture and second picture, and the picture of third picture
Face content and the first picture and second picture are all identical.That is the image content all same of three pictures, but image quality
It is different.For example the picture of the first picture of hypothesis, than more visible, the picture of second picture is relatively fuzzyyer, then third picture is by one point
Two parts that secant is divided into image sharpness different：A part of (the first display area) is because be derived from the first picture comparing
Clearly, another part (the second display area) is because be derived from second picture comparison is fuzzy.
Some drawing engines that above-mentioned technique effect can be provided using operating system are realized to realize.People in the art
Member is well known that, in area of computer graphics, coordinate origin (0,0) is in the upper left corner of drawing area, if the width of drawing area
Degree is width, is highly height, the coordinate in the lower right corner of drawing area is typically expressed as (width-1, height-1).
Assuming that the size of the first picture and second picture that network side is fed back is width*height, the embodiment of the present invention
The video comparison domain that video on browser is compared to interface is also initialized as width*height sizes.Cut-off rule can be
Horizontal linear or vertical line or broken line or curve.In order to enable the video person of comparison to carry out the first picture and second picture more
Add arbitrary comparison, the position of cut-off rule be can in response to the person of comparison operational motion and movement.
By taking vertical divider as an example.Assuming that it is desired that using a part for the first picture as the left half of third picture, by
The upper end point coordinates of right half of the part for two pictures as third picture, vertical divider is (w1,0), lower end point coordinates
For (w1, height-1), then the implementation method of the embodiment of the present invention can be：
The left half of the first picture is cut, i.e. top left co-ordinate is (0,0), and bottom right angular coordinate is (w1-1, height-1)
Part.Video comparison domain draw above cut out the first picture left half, be plotted to painting canvas [(0,0),
(w1-1, height-1)] region.
Cut second picture right half, i.e., top left co-ordinate be (w1,0), bottom right angular coordinate be (width-1,
Height-1 part).The right half that the second picture come is cut out on the drafting of video comparison domain, is plotted to painting canvas
The region [(w1,0), (width-1, height-1)].
If user drags the vertical divider, repeats to cut the left half of the first picture above and cut second picture
Right half operation, only the value of w1 changed.
Above in case of third picture is divided into left and right two parts by a vertical divider.User is according to specific
Demand can switch over contrastive pattern, for example be switched to vertical contrastive pattern, full frame/non-full frame contrastive pattern etc..This
Field technology personnel are readily appreciated that their implementation method, are no longer described in detail.
The drawing process of above-mentioned third picture can use HTML5 Canvas to realize, HTML5, that is, hypertext markup language
New standard, instantly most of browsers supported most of characteristics of HTML5, HTML5Canvas to be also known as HTML5 painting canvas, it
Two dimension or three-dimensional graphics images are drawn on webpage using JavaScript (script).General due to HTML5 is easy to get,
It realizes that the split of the first picture and second picture in the embodiment of the present invention is compared using its Canvas tools, the present invention can be made
Embodiment is preferably realized in the network environment for corresponding to different terminals platform.
Further, in response to user's operation, or according to the one or more rectangles for being pre-stored in the network side
The positions and dimensions data of frame draw one or more rectangles for reminding user to pay close attention in the video comparison domain
Frame.
These rectangle frames can arbitrarily be drawn with mouse in video comparison domain by user, and the purpose is to be used to remind to use
Family is paid close attention to by the region in rectangle frame.In case of image content includes face, user can be respectively in eyes, mouth
Lip etc. draws rectangle frame.Moreover, after user draws, the positions and dimensions data of these rectangle frames can be saved in net
Network side, when next user carries out similar operations, there is no need to repaint them.
For the needs of market competition and raising production efficiency, often there is different division of labor associations in the inside of Video Technologies S.P.A.
Make, someone is responsible for collecting the video file that same video content uses different coding algorithm to be obtained, these video files may
Part comes from rival, it is also possible to belong to our company, it may be possible to unprocessed form, it is also possible to optimize by certain encryption algorithm
Processing.After being collected into a pair of video file to be compared, further, someone is responsible for intercepting video to be compared from video file
Frame, someone are responsible for comparing these video frame and evaluate in turn the quality of encryption algorithm, and someone is responsible for exploitation and more preferably compiles
Code algorithm etc..The embodiment of the present invention adapts to this needs, and different functional roles is executed with end side and network side, because
And so that these work is cooperated by different people and complete.
Embodiment as shown in Figure 1 is as it can be seen that this video image quality applied to terminal provided in an embodiment of the present invention compares
Method, first from terminal browser by a pair picture to be compared obtained from a pair of video to be compared network side carry out storage and
Management obtains a pair of band to network side and compares picture and the progress split comparison on terminal browser thereafter.With existing skill
The stand-alone environment that is confined to of art is compared, due to the present invention is based on B/S, will storage and the function that manages compared be dispersed to terminal and
Network side realizes that video compares with terminal and network side, therefore can be well adapted for applying in the network platform.
When showing applied to network side referring to Fig. 2, Fig. 2, a kind of video applied to network side of the embodiment of the present invention
The flow diagram of image quality comparative approach, may comprise steps of：
S201, the video frame picture upload request that response terminal is sent by browser, so that terminal will be from video text
The video frame picture that acquisition is intercepted in part uploads；
Picture is uploaded to network side by user.The user for sending out video frame picture upload request may be two or more.
That is, entirely possible, by identical or different terminal browser, one or more users send out in the identical or different time
Go out picture upload request and final uploading pictures are to network side.Network side can be the different pictures wound from same video content
It builds one " picture group ", these pictures are all stored in this " picture group ", and user is in browser end it can also be seen that this " figure
Piece group ".
User can be the video frame figure other than selecting frame picture to be uploaded when browser end uploads frame picture
Piece provides a name, it is possible to specify which " picture group " picture is stored in.
S202 receives and stores the video frame picture that terminal is uploaded by browser；
Specifically, can be that picture is received by WEB server and picture is sent to application server；Application server will
Received picture is stored to database server.
Frame picture is sent to Web server, is then forwarded to application server, and application server arrives frame picture storage
In database server, such as MongoDB, a unique ID is generated to represent this frame picture, can use the ID later
To obtain the frame picture.
S203 receives terminal and is asked the download of a pair of video frame picture to be compared by what browser was sent, to terminal
A pair of video frame picture to be compared of feedback, so that terminal shows a pair of video frame picture split on terminal display screen to be compared
Compare so that user carries out video image quality；The pair of video frame picture to be compared includes the first picture and second picture, described
First picture is identical with the image content of second picture, intercepts obtain from the first video file and the second video file respectively；
First video file and second video file are that same video content handles regarding for acquisition via different coding mode
Frequency file.
Specifically, Ke Yiwei：WEB server receive terminal by browser send to a pair of video frame picture to be compared
Download request, according to downloads request to application server request picture；Application server is read to database server
A pair of video frame picture to be compared is sent to WEB server by a pair of video frame picture to be compared；WEB server is treated one
Compare video frame picture and feeds back to terminal.
First video file and the second video file may be that same video content is obtained via different coding algorithm process
Two files, it is also possible to one be video content unprocessed form, the other is unprocessed form is through certain Optimized Coding Based algorithm
Gained after processing.First picture is identical with the image content of second picture, but due to being by being intercepted respectively in different video file
It obtains, their image quality is different.By the comparison of the image quality to them, to judge the picture matter of different video file
The quality of amount, and the quality of different coding mode is judged in turn.
Identical first picture of image content and second picture, possible size simultaneously differ.This is usually because first regards
