Image Processing Results by David E. Pitts May 31, 2010 copyright 1999/2000/2001/2002/2003/2004/2005/2006/2007/2009/2010

Motion Smear Perform a DFT on the original image

Perform a DFT on a vertical line

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

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

Color Digitization with poor color quality

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

Stretch each color pdf between zero and 255 -Green

Stretch each color pdf between zero and 255 -Blue

Resulting in a much better image original final image

Another Example original final image

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