Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the embodiment of the present invention, is not intended to limit the present invention embodiment.
TV programme picture can be user intercept when watching TV and upload, also can be that editorial staff intercepts.TV programme picture can be used as the summary picture of TV programme (video of this TV programme).
Be illustrated in figure 1 the flow chart of the method for the process TV programme picture in the embodiment of the present invention, the method comprises:
Step S11: obtain TV programme picture.
Step S12: determine the background in TV programme picture.
Step S13: TV programme picture is classified according to the background determined.
Such as, the TV programme picture including identical and/or close background can be divided into a class.
In the embodiment of the present invention, classify according to the background in TV programme picture to TV programme picture, the TV programme picture of One's name is legion effectively can be classified, sorted TV programme picture is more conducive to management, searches and use.
Be illustrated in figure 2 the flow chart of the method for the process TV programme picture that another embodiment of the present invention provides, in this embodiment, comprise 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: carry out image recognition to the TV programme picture received, detects the prospect of TV programme picture.
Detect the prospect of TV programme picture, such as can prospect of the application extracting method.Foreground extracting method can be divided into foreground segmentation and prospect to scratch figure two class.Foreground segmentation has following several method: (1) is based on the dividing method of threshold value: the key of Threshold Segmentation Algorithm is definite threshold, if can determine that Iamge Segmentation just can come by a suitable threshold value exactly.After threshold value is determined, threshold value compared with the gray value of pixel and can carry out each pixel-parallel with pixel segmentation, the result of segmentation is directly to going out image-region.(2) based on the dividing method in region: region growing and split degree method are two kinds of typical serial regional development and technology.The basic thought of region growing is that the set of pixels with similar quality is formed region altogether.Split degree is almost the inverse process of region growing: from whole image, and constantly division obtains each sub regions, and then foreground area is merged, and realize target extracts.(3) based on the dividing method at edge: different gradation of images is different, and boundary generally has obvious edge, utilizes this feature to split image.Conventional first order differential operator has Roberts operator, Prewitt operator and Sobel operator, and Second Order Differential Operator has Laplace operator and Kirsh operator etc.In addition the edge detection method based on mathematical morphology, the edge detection method based on genetic algorithm is also had, based on fractal edge detection method etc.(4) based on the dividing method of particular theory, image partition method as based on cluster analysis: it is the characteristic of correspondence spatial point of the pixel in image space represented that feature space clustering procedure carries out Iamge Segmentation, according to their gatherings at feature space, feature space is split, then they are mapped go back to original image space, obtain segmentation result.Dividing method as based on wave conversion: basic thought is the wavelet coefficient first by dyadic wavelet transform, the histogram of image being decomposed into different levels, then select threshold value thresholding according to given segmentation criterion and wavelet coefficient, finally utilize threshold value to mark the region of Iamge Segmentation.Dividing method based on neural net: basic thought obtains linear decision function by training multi-layer perception (MLP), and then classifying to pixel with decision function reaches the object of segmentation.
Step S23: leave out the prospect detected in TV programme picture.
Step S24: the background TV programme picture of leaving out prospect being defined as TV programme picture.
Step S25: the TV programme picture with close background is divided into a class.
In an alternative embodiment of the invention, judge that whether the background of TV programme picture is close and can use following methods: the color histogram obtaining the background in TV programme picture; The TV programme picture similarity had between color histogram being less than the background of preset value is divided into a class.
Be illustrated in figure 3 the flow chart of the method for the process TV programme picture that another embodiment of the present invention provides, in this embodiment, comprise 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 the background determined.
Step S34: the background of sorted TV programme picture is mated with the studio backgrounds preset, determines the channel belonging to TV programme picture and/or program.
After determining the channel belonging to TV programme picture, program, functions such as searching can be realized further.Such as, after TV programme picture classification, there is the background of the TV programme picture of a class to be background between the live news of " morning news " of news channel, so can determine that such TV programme picture belongs to " morning news " this program further.In other embodiments of the invention, sorted TV programme picture can also be mapped with the program belonging to it, such as, in TV programme picture, add the label of corresponding program.So, when TV programme picture searched by needs, can input " morning news ", just can find the TV programme picture belonging to " morning news " according to label.The TV programme picture that the present embodiment is specially adapted to belonging to channel and/or the program with fixed background is classified.
