Dear Mr. Art Tevs,
I have been able to incorporate osgPPU into my application. Image filtering
and color space conversions are working fine for a desired resolution that I
set at the beginning of the osgPPU Pipeline. Further I am facing a few problems
in which respect I would like your kind suggestions
1. We require to carry out filtering at a higher resolution followed by sub
sampling. Can you suggest a method to sub-sample the image to a lower
resolution.
2. We need to stretch the contrast of the image. Earlier we were doing this
on CPU. We build a histogram of the image, identify the lower and higher gray
levels, followed by the pixel by pixel transformation of gray levels.
It would be very kind of you if you can suggest appropriate methods, or
else if you can indicate suitable pointers
Regards
Harash
