    control points in the source and destination image The subsequent marks will be in red green blue and yellow If you want to map your source image onto another destination image you can mark your 4 controlpoints in the destination image first You can then exit the plug in to switch to the source image The restart the plug in to mark your 4 controlpoints in the same order in the source image Your source image is then ready to be warped Press the Preview button to see the result without leaving the plug in or press Warp to warp the original image and exit the plug in The try out version only shows the warped image in the preview Your current controlpoints are always stored and you can save them in a file of your choice a textfile with wrp as its extension Of course you can open those files as well so your warping is documented completely Delete last works like a Backspace on your controlpoints while Delete all deletes all controlpoints in either your source or destination image Hints The parts of the warped image for which no information is available will be black if your original

    diagonal pattern in the source image by painting away the lower frequencies associated with it near the center of the image You can paint over with black or as in this example use the clone brush N B Don t forget to select all channels before you transform back by clicking on RGB In the resulting image after applying the inverse FFT the diagonal pattern has been suppressed Click on the image to see the original and observe the improvement Using the same procedure can also remove the screening pattern in the Fourier transformed image This time we remove the repeated patterns surrounding the central pattern using for example the healing brush of Photoshop Click on the image to see the original and observe the improvement Download the Fourier Transform plug in so you can use it with your host application Understanding the Fourier transform The Fourier transform decomposes a waveform or function into sinusoids of different frequency which sum to the original waveform It identifies or distinguishes the different frequency sinusoids and their respective amplitudes The Fourier transform of an image is itself an image where each pixel corresponds to the intensity of a frequency Thus locations in the Fourier transform image identify periodicity and orientation from any or all parts of the original image The Fourier transform can help us to detect periodic structures that need to be enhanced and possibly those we want to get rid of This is an example of a 2D sinusoid sheet with brightness converted to height The original image is given by the sum of all sinusoid sheets Each of these sheets is given by the following properties frequency distance to center amplitude brightness in the red channel phase brightness in the green channel orientation direction of the radius from the center
