I'm very new in gis, and i'm trying to find a fast solution to merge 200 historical areal images(black and white from 1944). I orthorectified them manually, using gcp-s. They have 1 to 10 meters error. So I cannot use simple mosaicing software. I want to use roads as boundaries. Is there any os software what can help me in this? Or shell i cut them by myself, and merge them together with qgis for example?
Bonus question: Is there any automated contrast and brightness balancer for this amount of images?
