I'm processing lots of USGS NAIP imagery which overlaps. if I load multiple files into a QGIS project I can clearly see the edges of each tile being that some tiles have a darker or lighter contrast than neighboring tiles.
by using GlobalMapper I'm able to put a fade around all of the edges of the tiles to basically fade them together. but I'm getting away from that method to create a full script to handle my proccess much easier. is there a way to "fade" or "blend" the edges together using gdal or maybe do some type of histogram correction?
