WebThe Dark Object Subtraction method assumes that the darkest parts of an image (water, artificial structures) should be black if not for the effects of atmospheric scatter. Corrections to make it possible to use the black value from one band to correct the remaining bands. Value Author (s) Sarah Goslee References Chavez, Jr., P. S. 1988. WebThe dark count may be subtracted if a dark count image is available that exhibits less noise than the dark count contribution in the image being processed . This last point is very important; if the dark count image to be subtracted has more noise than the image to be processed, then subtraction will actually lead to an increase in noise!

WebThe “dark object value” in each band can then be subtracted from all image values to produce a path-radiance corrected image. The Dark Object correction can be applied to reflectance and/or output radiance rasters. Dark object values can be determined in several ways, specified by the selection on the Dark Object menu in the Correction box.
