[Solved] Image processing Project #1

Consider intensity transformation function, s = T(r) = H{arctan[(r128)/32]}, where H{} is a linear operation used to shift and rescale the result of arctan to make the final value s in the range 0 255 (same as the range of input intensity r).

Determine

• the transformation function s = T(r),
• the output image after applying the transformation function to the image below, and
• the input and output histograms.

Your report (Word or pdf format) should contain:

• Source codes
• Figure of s = T(r)
• Table of transformation function to show the mapping from the input gray level r to the output gray level s
• Figure of the output image after applying the intensity transformation function
• Figures of the original and output histograms
