I have used around 200 sqkm high resolution single band colour Bing image for object based image analysis on ecognition developer. But due to different tile based exposure made it worse to classify. the segmentation goes different for two areas. Can anyone suggest how to pre process the image before segmentation. I have added an example of exposure problem through image. 
I have used ecognition developer provided equalizing tools like Gamma Correction, Histogram, linear equalizer and standard deviation. But nothing works.
