Problems solved by technology

[0006] In the prior art, the characteristics of static pictures are used to identify the characteristics of advertisements, which cannot effectively identify advertisements in dynamic video streams; moreover, these existing identification technologies process a large amount of data in the data stream one by one. The amount of calculation is large, the time required is long, and the requirements for equipment are high

Embodiment 1

[0087] Compatible with the above method embodiments, the present invention also provides an image feature recognition device, as shown in Figure 3, which is Embodiment 1 of the device of the present invention, including:

[0088] A cut frame identification unit 301, configured to: identify a cut frame of the current video file;

[0089] A cut frame feature acquisition unit 302, configured to: acquire the image feature of the cut frame;

[0090] The matching unit 303 is configured to: if the image feature of the cut frame matches the preset image feature, then the image feature of the current video frame is consistent with the preset image feature.

[0091] First, in this embodiment, by identifying the shear frame of the current video file, and obtaining the image features of the shear frame, by comparing the acquired image features of the shear frame with the preset image features, when the two are consistent At this time, the identification of the image features contained in...

Abstract

The present invention embodiment discloses a method for identifying image characteristics, which includes: identifying shear frame of current video file; obtaining image characteristic of said shear frame; if image characteristic of said shear frame matching with pre-set image characteristic, image characteristic of said shear frame is in accordance with pre-set image characteristic. The invention also provides a identifying device of image characteristic. A specific file can be identified by judging the shear frame whether having specific image characteristic, instead of identifying image characteristic of each video frame, and large calculation amount is reduced. So the calculation is fast with high efficiency.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image feature recognition method and device. Background technique [0002] Now with the extensive development of various media, especially the technology of conveying information by means of images is increasingly developed. Both consumers and media operators have benefited greatly from it. However, the most popular media now basically broadcast sponsors' advertisements. For various needs, it is necessary to identify the characteristics of advertisements therein. The existing technical solutions mainly include: [0003] A technology for identifying advertisements is to identify advertisement features by using the features of static pictures, which makes it impossible for existing technologies to effectively identify advertisements in a video; for example, different advertisement segments of the same product, some of which The pictures will be exactly the same, but...
