4802-6-2: Frequency Domain

Weblinks gathered by Shawn Davis

Summary

This lecture focused on the topics of frequency domain and portions of Fourier transform theory.

Frequency Domain

Frequency domain can can help completely specify an image provided that enough sinusoids are found and high frequencies can be obtained. The following links provide information about frequency domain.

http://orca.cs.byu.edu/morse/550-F95/node18.html contains high/lowpass filtering descriptions and theories for image processing [4]
http://www.ee.princeton.edu/~icip95/iplink/index.html this is an excellent resource for many image processing links. Instead of picking and choosing specific ones, the main page is listed and research can be done from there [5]
http://www.ph.tn.tudelft.nl/Courses/FIP/frames/fip-Convolut-2.html information on convolution-based operations, small discussion of spatial and frequency domain and Fourier transforms [2]

Fourier Transform

Given an image, the Fourier transform is a mathematical technique for finding its basis functions. The following links provide information about Fourier Transforms.

http://robotics.eecs.berkeley.edu/~sastry/ee20/vision2/vision2.html information on Fourier transforms, including 2-D and other mathematical theory [4]
http://archives.math.utk.edu/topics/fourierAnalysis.html mathematical links pages, which includes Fourier analysis and some image processing links [4]
http://www.ph.tn.tudelft.nl/Courses/FIP/frames/fip-Properti-2.html properties of Fourier transforms, math is a little tricky, but great theory [5]
http://www.rose-hulman.edu/~hoffmake/index.html student homepage, but has excellent examples of Fourier transform results and frequency domain graphs for those who wish to visualize the results of using these techniques [5]
