Embodiment

[0068] 1. Test platform:

[0069] Test Platform: Server - Smart TV.

[0070] 2. Test case:

[0071] Test range: 60 channels

[0072] Test pictures: We mainly grabbed live TV pictures from CNTV China Live TV. We grabbed 6 pictures for each channel, and a total of 360 test pictures.

[0073] 3. Correct recognition rate and unrecognized rate:

[0074] Test results: the success rate can reach more than 95%; the error rate is reduced to 0; the unrecognized rate is 5%. For the unrecognized 5%, we can use multiple recognition methods to finally recognize all the logos.

[0075] 4. Method identification time

[0076] The method recognition time refers to the algorithm processing time of the station logo recognition module in the system, excluding the transmission time.

[0077] Recognition time: 2ms~3ms.

[0078] The method proposed by the invention has improved accuracy rate and time performance. In the specific implementation, the logo recognition process can be taken as a s...

Abstract

The invention relates to the technical field of digital image processing, in particular to a station logo recognition method and a recognition system thereof. The recognition method includes the following steps based on the recognition system: A. Constructing a TV station logo sample library, and storing the sample library in the server; B. Grabbing target images containing station logo information; C. Intercepting stations containing station logo information. image; D, converting the target image into a grayscale image; E, performing image scaling on the grayscale image; F, using a threshold comparison method to identify a station logo. The present invention proposes that the accuracy rate and time performance are both improved. In the specific implementation, the station logo recognition process can be taken as a separate process, and it can be carried out synchronously when the TV main program searches for analog signals, so that it does not affect the user's use. One-time identification of the station logo and push of EPG information are completed. For the translucent station logo and the background image of the station logo are relatively complex, the recognition accuracy is high and the processing speed is fast.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a station logo recognition method and a recognition system thereof. Background technique [0002] The station logo in the television video is a sign of a television station, indicating important information such as the station name and program orientation of the television station. In some scenarios, the smart TV does not know the information about the TV station currently playing the program, such as 1. when the smart TV receives an analog signal, and 2. when the smart TV receives a signal transmitted by a set-top box. [0003] If the station logo can be correctly identified in the above scenario, then the program timetable, program poster, and program introduction information of the TV station can be provided according to the station logo, and the user can obtain a good experience. [0004] The station logo recognition belongs to the category of image matching...
