Recovering missing pixels for a Landsat SLC-off image using Weighted Linear Regression and accuracy assessment of land cover map (Case study: Khoy region, Northwest Iran)
On May 31, 2003 the Scan Line Corrector (SLC) in the ETM instrument on Landsat 7 failed. Until now, a wide variety of gap-filling methods have been developed to recover missing pixels in the Landsat 7 SLC-off images. In present study, a newly-developed approach known as the Weighted Linear Regression (WLR) method was evaluated on the simulated SLC-off TM image acquired on 18 June 2011 when plants and vegetated lands are growing. The statistical measures of the RMSE (
