Embodiment Construction

[0030]Please refer to Figure 1, which is a block diagram of a television news segmentation system. The system 10 segments TV news by detecting TV news anchors. The system 10 includes an image processing circuit 30 , and the image processing circuit 30 generates candidate segments 40 of news images according to the detection results of the TV news anchors. Once the candidate segment 40 of the news image is generated, the sound information of the candidate segment 40 will be further analyzed to ensure the correctness of the image analysis.

[0031] The image processing circuit 30 includes a lens detection circuit 32 , a facial skin color detection circuit 34 and a subsequent processing circuit 36 ​​. The facial skin color detection circuit 34 is used to detect pixels falling on the image frame within a predetermined range, and the predetermined range represents the skin color range. Please refer to FIG. 2 and FIG. 3 . FIG. 2 shows whether there is a facial image of a TV news an...

Abstract

The method comprises: using a first horizontal scan line to scan the pixels in the image; deciding if the color of the pixels are located in a preset color range; using the pixels on the first horizontal scan line in multi continuous images to generate a color map; if the color map shows that the continuous images all include stable pixel area, and the pixels all are located in the preset color range, then the current image fragment is marked as a candidate fragment; making color comparison for color spectrum curve in the stable pixel area to detect the lens transition.

Description

technical field [0001] The invention relates to an image segmentation technology, especially a method for detecting TV news anchors and segmenting TV news programs. Background technique [0002] As the number of news channels on TV increases day by day, more and more news information can be obtained, so it is becoming more and more difficult for viewers to search and find the news programs they want. A news program usually contains several different pieces of news, and usually there is not much connection between each piece of news. In order to make it easier to search and sort each piece of news, images of TV news anchors can be used to identify when each piece of news starts and ends. Therefore, in each news segment, the shot of the TV news anchor becomes the most important shot. The TV news anchor usually makes an introduction at the beginning of each segment of news, or comments or sorts out the news content at the end of each segment of news. Therefore, the TV news an...
