Problems solved by technology
[0004] In reality, there are a large number of cases where the logos of different channels of the same TV station are similar to each other, such as CCTV1, CCTV2, CCTV3, etc. Approximate station logos often have a high global similarity, which is easy to confuse
In the prior art, when it is necessary to obtain multiple approximate station logos, the usual method is to extract multiple station logos separately. Since this extraction method cannot utilize the similarity of the approximate station logos, the extracted The content is often repeated many times, which greatly increases the extraction time of the logo and reduces the extraction efficiency

Embodiment Construction
[0055] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0056] The present invention provides a processing method for approximating station logos, such as figure 1 Said, including the following steps S101-S104:
[0057] Step S101: According to the image information of the first logo, obtain the pixel value of each line of the first logo;
[0058] Step S102: Match the pixel value of the first line of the first logo with a frame of image containing the second logo, and determine the area where the second logo is located;
[0059] Step S103: In the area where the second logo is located, match the pixel values of the other lines of the first logo with the frame of image containing the second logo, and determine the relati...

The present invention discloses a processing method of approximate TV logo and a device to modify a known TV logo and obtain an approximate TV logo so as to realize the rapid and accurate obtainment of the TV logo. The method comprises the steps of (A) according to the image information of the first TV logo, obtaining the pixel values of each row of the first TV logo, (B) matching the pixel values of the first row of the first TV logo and a frame of image comprising a second TV logo, and determining the area of the second TV logo, (C) in the area of the second TV logo, matching the pixel values of other rows of the first TV logo and a frame of image comprising the second TV logo, and determining the image difference between the first TV logo and the second TV logo, and (D) obtaining the different pixel value of the first TV logo and the second TV logo according to the image difference, and modifying the first TV logo according to the different pixel value, and obtaining the second TV logo.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a processing method and device for approximating a station logo. Background technique [0002] The station logo is a visual watermarking technology, which is often added to TV video files to declare the property rights and content attributes of TV videos, so that TV stations can be distinguished from other organizations with different graphic signs. The TV station logo has increasingly become an important factor for channel specialization and brand building. With the continuous development of the radio and television industry and industrial reform, and the continuous innovation of video technology, various media companies emerge in endlessly, and the number of TV channels continues to increase. , and the number of Taiwan logos has also continued to rise. [0003] The station logo is a symbol of a TV station, which contains important semantic information such as the stat...
