2. Motion Smear
Perform a DFT on the original image

3. Perform a DFT on a vertical line

4. Multiply the two FFT images together, take
the inverse DFT, and swap quadrants.
Thus giving an image blurred in the vertical direction
Product Inverse DFT Swap Quadrants

5. Likewise using a horizontal line gives an image
blurred in the horizontal direction

6. Color Digitization with poor color quality

7. Stretch each color pdf (probability density function) between zero and 255 using "Adjust Brightness/Contrast Levels" in Photoshop
-Red

8. Stretch each color pdf between zero and 255
-Green

9. Stretch each color pdf between zero and 255
-Blue

10. Resulting in a much better image
original final image

11. Another Example
original final image

12. RGB (Red, Green, Blue) conversion to
HSI (Hue, Saturation, Intensity)
