I have a large set of raster images (they are aerial imagery) and they were taken under various different light conditions. I would like to use histogram equalisation to correct for this. Does anyone know if this is possible in FME please?

I'm not sure about RGB images but I've done it for greyscale with the RasterExpressionEvaluator. Can't seem to find the workspace right now that does that so I can't tell you the formula.

 

But that's basically it, if you know which formula to use on the various bands you can use the RasterExpressionEvaluator to perform that action.
