Experiments in altering pixel intensity of images. PixelIntensityBW.C changes intensity in gray scale images. PixelIntensityBW.C takes two parameters, contrast and brightness, and adjusts these values in color images. The sample results show a high-lighted region using specific contrast and brightness values. Additionally, there has been some noise applied in the high-lighted region. The rest of the image outside the region has lowered intensity.
