PiX, a collection of batch utilities for GNU/Linux and similar platforms, creates mathematically accurate figures, plots, and movies using easy-to-learn syntax. The output is expressly suitable for use with LaTeX; figures may be written in a LaTeX picture environment containing PSTricks, tikz, or eepic macros, or as vector (EPS or PDF) image files.
FUBAR uses the statistical technique "Kriging" to rescale images with an global geometric pattern, called the variogram.
The image can be infinitely rescaled: the estimates ('o' on the left figure) are calculated from five neighbouring samples of the source image ('+' on the left figure). The image is 'noisy' because each pixel is a realization of the estimated value. In other words, each pixel is a random value with a mean and a variance from the local distribution. By changing the variogram (press 'v') or the variance multiplier, it is possible to control that variance.
Clicking the left mouse button zooms in on the image and right-click zooms the image back out. Press SPACEBAR to accept the current realization as the 'source image' -this will reduce noise at small scales.
The GIMP (GNU Image Manipulation Program) is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.
GIMPshop is a modification of GIMP, intended to replicate the feel of Adobe Photoshop. Its primary purpose is to make users of Photoshop feel comfortable using GIMP...Many Photoshop tutorials can be followed in GIMPshop...
Yes, another attractor visualizer, but glChAoS.P allows you to explore interactively any attractor type, modifyng linearly the values and displaying the changes obtained, immediately, in 3D and in realtime.
Open source graph visualization software. Takes descriptions of graphs in a simple text language, makes diagrams formatted as images, SVG for web, PS for PDF, GXL (XML dialect), and more.
