Embodiment
Below in conjunction with specific embodiment, technical solution of the present invention is further illustrated.
The specific embodiment of the present invention is: a kind of rating analytical method based on video features and user profile is provided, comprises television terminal 2 and server end 1, described rating analytical method supplying method comprises the steps:
Store video characteristic: the video frequency feature data of described server end 1 store video programs.
Specific implementation process is as follows: the characteristic of described server end 1 store video programs, the characteristic of described video frequency program comes from the video frequency program feature that server end 1 gathers, and also can come from outside and be sent to the video frequency program characteristic on server end 1.The characteristic of described server end 1 store video programs.That is, this characteristic, corresponding to its corresponding video frequency program, can know by this characteristic the video frequency program that it is corresponding.Video frequency feature data, be the set of video image characteristic, means the data of this section video frequency program feature.Video frequency feature data comprises the comprehensive characteristics set of various video characteristics of image, such as average gray feature, color moment feature, HOG feature etc., the representative of average gray feature means the intensity profile situation of video image, the situation that in color moment character representation video image, color component changes, the situation of grey scale change in HOG character representation video image.By the video features of each two field picture in continuous calculating video flowing, and these characteristics are preserved, just can obtain the characteristic data flow of video, thereby mean this video.Usually in algorithm, average gray is characterized as the average gray value of image, and the average gray value of image is the average of all gray value cumulative sums in certain zone, and average gray value has characterized the average color depth degree of this area pixel point, its span [0,255].For entire image, this is the feature (each piece has 1 average gray value) of one 9 dimension.
The HOG feature is based on the feature of gray level image, for pixel, by formula, calculates gradient direction k and amplitude S, specifically is calculated as follows:
Color moment in the color moment feature has the good characteristics such as translation, rotation, convergent-divergent consistency, calculates its first three Jie center square, and for entire image, the feature that conventional algorithm is a 3*3*9=81 dimension specifically is calculated as follows:
Gather and upload audience information: gather the video frequency feature data of user profile and current video program, the video frequency feature data of collection and user profile are uploaded to described server end 1.
Specific implementation process is as follows: while opening television terminal 2, gather the video frequency feature data of current displaying video programs, by the video flowing of inputting described television terminal 2, gather video frequency feature data.Gather user profile, described user profile comprises in age bracket under user's sex, age of user, user, user watched time, user's occupation attribute any one or a few.The video frequency feature data of collection and user profile are uploaded to described server end 1.
Rating is analyzed: the video frequency feature data of the video frequency program of 1 pair of video frequency feature data of uploading of described server end and storage compares analysis, described server end 1 determines according to the comparative analysis result video frequency program that described television terminal 2 is play, the audience ratings that obtains this video frequency program according to rating time and the user profile of video frequency program and according to the viewership of user profile classification.
