My boss asked me to mosaic and color-balance multiple Landsat 8 tiles for presentation. I tried to do that in ERDAS but it returned weird result as below:
Obviously it's the black edges or nodata pixels were counted while balancing the color. Is there a way to eliminate those annoying pixels?
The tiles were exported from the direct 16-bit USGS ".tar.gz" data files into 8-bit images. And the 8-bit images were then brought in to the Mosaic Pro session for color correction. All processes were done by ERDAS. However I also tried to export the 8-bit images through ArcGIS and then process in ERDAS Mosaic Pro but the result was the same.
Answer
Number 1: what version are you using ?
Number 2: Don't use the AOI as it is diffcult process to do for more than 2 images.
Number 3: Scroll down to page 18 as it is giving you how to mosaic many images http://www.gis.usu.edu/~alex/WILD6750/Lab05/Lab05/Lab5_Mosaic_TourGuide.pdf
