Info

Now the DEM can be used to conduct a haze reduction on the image. Openyour two data files, opening the RGB color composite image first and the DEMimage second. Select ‘Pre Process | ‘Haze Reduction’ | ‘DEM Method’. A dataentry box will be come visible as shown below.151
The correction is made according to the equation suggested by Hormann:Adjusted Pixel(x,y) = Pixel(x,y) - pow(Pixel(x,y),Exponent)*Weight*HRel(x,y)WhereHRel(x,y) = (HRef-Height(x,y))/HRefWhere HRef is the elevation at which no correction is necessary. An exampleof a corrected image is shown below.152
