Analysis of scan stripe noise in Landsat TM images

In Landsat TM images, scan stripe noise often appears every 16 lines at the both side of white object such as cloud, which not only visually degrade the images but also make the quantitative analysis difficult. As the scan stripe is considered to be a sensor related noise, it cannot be removed by the image processing technique without considering its physical mechanism. In this paper, we assume the impulse response of AD converter as the noise source, and model the scan stripe noise as well as scan direction difference mathematically. The parameters of the response function are estimated from the night time data and they are applied to the day time data to remove the scan stripe noise.
