Method for detecting bands in video images

The invention discloses a method for detecting bands in video images. The method comprises the following steps: 1, allowing a user to choose the color and type of a to-be-repaired band according to band characteristics appearing in a video sequence and to determine a detection region according to a position where a band in a first frame appears; 2, judging the choice of the user and entering a step 3 for processing if a vertical band is chosen or entering a step 4 for processing if a horizontal band is chosen; 3, detecting the vertical band to obtain a band template drawing, generating the detection region of next frame and cyclically using the step to process follow-up frames; and 4, detecting the vertical band to obtain the band template drawing and cyclically using the step to process the follow-up frames. Compared with other band-detecting methods in the prior art, the method has the advantages of detecting various bands in the video images, improving reliability, allowing users to only need to perform in
