The script is useful to work on the two images of stereo pairs using the gimp, after handling the two images as separate layers during editing, this script can be used to convert two layers back into one stereo image.
This script converts two equal sized layers being positioned above each other, into one stereo image with the two former layers positioned next to each other:
1. the user choses one of two piled layers to be moved to the right of the other layer
2. the script repositions the chosen layer next to the right border of the other layer
This script generates a pattern like the one shown in the attached png. The size of the image can be anywhere from 300x300 to 3000x3000. The pattern can be symmetric, or it can be weighted to have longer sides on one side. The color of the lines in selectable. I'm not sure what this can be used for, but it does make a nice pattern that can be tiled. Enjoy!
A simple plug-in to convert RGB images to YUV in GIMP. This means that after having applied the filter, you will get luminance (Y) in the red channel (R), and chrominances in green and blue channel. By using the decompose plugin, or the channel dialog, you will be able to work in YUV space, and be back in RGB space by the reverse plugin.
A simple plug-in to do fourier transform on you image. The major advantage of this plugin is to be able to work with the transformed image inside GIMP. You can so draw or apply filters in fourier space, and get the modified image with an inverse FFT.
The wavelet sharpen plugin enhances apparent sharpness of an image by increasing contrast in high frequency space. The amount of unsharpness of the original image can be taken into account by adjusting the sharpening radius. As an option you can choose to sharpen the luminance (YCbCr) channel of the image only.
This script will make a single eyeball, and has been updated for v2.6. The colors of the iris, and size of the pupil, lighter iris, and darker iris, are all adjustable. Ideally, the inner eye color should be about half the brightness of the outer eye color to provide a nice transition from the pupil, but any two colors can be used. The image itself can be anywhere from 300x300 to 3000x3000 in size. The eye will have a transparent background. Enjoy! The attached picture is what the final product will look like (your colors may vary, obviously!)
"Scale in steps" resizes an image to the given dimensions in several steps to get a way sharper result compared to resizing in one step. The step size is given in percent and should range between seven and ten percent.
None of the sample images are sharpened. The original picture was 3000×2000.
