摘要
提出了一种从图像处理角度检测重影画面的方法.该方法以台标作为基准物,在HSI(hue saturation intensity)空间界定提取颜色的范围,根据台标区域中具有提取颜色的像素数目与固定阈值的比较,识别出重影画面.从实验结果可知,该方法对于重影画面的检测是有效的.
This paper gives a method to inspect the ghost images on TV set from the perspective of image processing. The TV station sign is used as benchmark, and we get the scope of each color in the HSI color space. Then we compare the amount of pixels of each color with a constant threshold in the TV station sign area and recognize the ghost images. The result shows the method is effective to the most of the ghost images.
