Abstract EN
After the month of May 2003, the satellite images obtained by the sensor ETM + and of the satellite Landsat 7 affected significantly because of Alakecl in the system debugger scanner linear system's scan line corrector SLC which results through a set of rows or images that contain a zigzag pattern along the ground track to the moon and those rows and images Thnue loss and repetition in the data , which are clear along the edges of Eastern and Western scene space satellite scene)) and at least gradually decays toward the center of the scene space.
These images contain 22% of the black lines (system's scan line corrector SLC-off) and this needs to be addressed especially to remove the effects.
There are several methods developed to address those lines of those ways is Mullah (Filling) for data lost by relying on the generation of lines scanned neighboring Neighboring scan lines)) The second way is up Bastbdl pixels lines black Bpeixlat taken from images of the same area taken shortly close before or after Date of the image that are meant her make the correction in both methods is to compensate for the lost original values , so the image quality is less than the corrected sound.
The origin of the idea is that the satellite image is composed of a matrix of pixels Pixels , each of which has a numeric value DN value, and the numeric value of the pixels black lines be zero , which means the loss of data floor areas located within those lines.
The idea of the treatment process is the replacement of the pixels in those black lines with another sound and images taken one or more of the same area and the same sensor accuracy and spatial Spatial resolution itself , preferably those pictures may be taken immediately before or after the image of the black lines .
The reason for this is that there be no significant variation in the parameters of land cover
