Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
It applies example and is merely to illustrate and explain the present invention embodiment, be not intended to limit the present invention embodiment.
TV programme picture is intercepted and is uploaded when user watches TV, can also be editorial staff and intercept.
TV programme picture may be used as the abstract picture of TV programme (videos of the TV programme).
It is as shown in Figure 1 the flow chart of the method for the processing TV programme picture in the embodiment of the present invention, this method includes：
Step S11：Obtain TV programme picture.
Step S12：Determine the background in TV programme picture.
Step S13：TV programme picture is classified according to determining background.
For example, can will include that the TV programme picture of identical and/or similar background is divided into one kind.
In the embodiment of the present invention, classified to TV programme picture according to the background in TV programme picture, can be incited somebody to action
Large number of TV programme picture is effectively classified, sorted TV programme picture be more advantageous to management, search and
It uses.
It is illustrated in figure 2 the flow chart of the method for the processing TV programme picture of another embodiment of the present invention offer, at this
In embodiment, include the following steps：
Step S21：Receive the TV programme picture that user uploads.
The TV programme picture that user uploads can be that user's screenshotss when watching TV generate.
Step S22：Image recognition is carried out to the TV programme picture of reception, detects the foreground of TV programme picture.
The foreground for detecting TV programme picture, can be used for example foreground extracting method.Foreground extracting method can be divided into
Foreground segmentation scratches two class of figure with foreground.Foreground segmentation has following several method：(1) dividing method based on threshold value：Threshold segmentation
The key of algorithm is to determine threshold value, accurately divides the image into and comes if it can determine that a suitable threshold value.Threshold value is true
After fixed, threshold value can to each pixel-parallel be carried out compared with the gray value of pixel with pixel segmentation, the result of segmentation is direct
Provide image-region.(2) dividing method based on region：Region growing and split degree method are two kinds of typical serial region skills
Art.The basic thought of region growing is that the pixel set with similar quality gets up to constitute region.Split degree is almost
The inverse process of region growing：From whole image, constantly division obtains each sub-regions, then foreground area is merged again,
Realize Objective extraction.(3) dividing method based on edge：Different gradation of images is different, and boundary generally has apparent edge,
It can divide image using this feature.Common first order differential operator has Roberts operators, Prewitt operators and Sobel to calculate
Son, Second Order Differential Operator have Laplace operators and Kirsh operators etc..In addition there are the side edge detections based on mathematical morphology
Method, the edge detection method based on genetic algorithm, based on the edge detection method etc. for dividing shape.(4) segmentation based on specific theory
Method, such as image partition method based on clustering：Feature space clustering procedure progress image segmentation is will be in image space
Pixel is indicated with corresponding feature space point, is split to feature space according to their aggregations in feature space, then will
They map back artwork image space, obtain segmentation result.Such as dividing method based on wave conversion：Basic thought be first by two into
The histogram of image is decomposed into the wavelet coefficient of different levels by wavelet transformation, then according to given segmentation criterion and wavelet systems
Number selection threshold value thresholding, finally marks the region of image segmentation using threshold value.Dividing method based on neural network：Basic thought
It is that linear decision function is obtained by training multi-layer perception (MLP), is then classified to pixel with decision function to reach segmentation
Purpose.
Step S23：Leave out the foreground detected in TV programme picture.
Step S24：The TV programme picture for leaving out foreground is determined as to the background of TV programme picture.
Step S25：TV programme picture with close background is divided into one kind.
In an alternative embodiment of the invention, following methods can be used by judging whether the background of TV programme picture is close：
Obtain the color histogram of the background in TV programme picture；Preset value will be less than with the similarity between color histogram
The TV programme picture of background is divided into one kind.
It is illustrated in figure 3 the flow chart of the method for the processing TV programme picture of another embodiment of the present invention offer, at this
In embodiment, include the following steps：
Step S31：Obtain TV programme picture.
Step S32：Determine the background in TV programme picture.
Step S33：TV programme picture is classified according to determining background.
Step S34：The background of sorted TV programme picture is matched with preset studio backgrounds, determines electricity
Depending on the channel and/or program belonging to program picture.
Channel belonging to TV programme picture is determined, after program, can further realize the functions such as lookup.Example
Such as, by the new of " morning news " that the background for after TV programme picture classification, having a kind of TV programme picture is news channel
The background for hearing direct broadcasting room, then may further determine that such TV programme picture belongs to " morning news " this program.
In the other embodiment of the present invention, can also by sorted TV programme picture with its belonging to program be mapped, for example,
The label of corresponding program is added in TV programme picture.So, it when requiring to look up TV programme picture, can input
" morning news ", so that it may to find the TV programme picture for belonging to " morning news " according to label.The present embodiment especially suitable for
TV programme picture to belonging to channel and/or program with fixed background is classified.
