摘要：Due to narrow-band noise signals in transmission channels, visible lines of disturbance can appear in video images. In this paper, an adaptive method based on two-level filtering is proposed to enhance the visual quality of such images. In the first level, an adaptive orientation selective filter detects and clears the noisy lines in the image. In the second level, a median filter repairs defects resulting from the orientation selective filtering process and also filters the wide-band impulsive noise. It was observed that in case of periodic noisy lines in TV images, this filtering technique can sufficiently enhance the image quality and improve the SNR level.
