I am having problems with mosaicing Ikonos and QuickBird imagery. These
images were acquired on different dates (though some follow a common
flightline) and have different contrast/brightness. I am trying to mosaic
these to form a composite image with good color balance that doesn't look
like a jigsaw puzzle. The study areas require mosaicing 3-4 images for
Ikonos and 5-7 for QuickBird imagery.

I have used most of all methods/options in Erdas Imagine and have not been
successful, even with manual color balancing. Have any suggestions? Also,
if you've seen image sets which have been mosaiced for purposes of
classification, are you aware of what the effects are on accuracy etc?

Thanks,
Sunil

i'm having the same situation also. if u found any idea, please inform me. color balancing is a bored job.
