Gaussian Image Write a program to create an image having a gaussian intensity. That is, the brightness function should be
where x0 and y0 are the image center locations, A is a constant chosen to produce white at the image center, and s is a scale parameter. Try producing images using various values for s.
Gaussian Transform
Show that when x0=y0=0, the Fourier transform of the gaussian brightness function f(x,y) given above is
Hint: Treat the integration by x and y separately. You may find it helpful to use equation 15.73 of Schaum's Mathematical Handbook,
Median Filtering
Write a program which implements median filtering.
Apply it to the images
king1.img
and
king2.img.
Notice, in particular,
what happens to the uniform areas of the image (the wall in back).
The original
image king.img is
in the image archive.
What happens if you apply median filtering to an image that contains
significant small features, such as
galaxy.img
in the image archive?
Apply it to the image
galaxy.img to find out.
