ImageJ

Description:

Data Types: 8-bit grayscale or indexed color, 16-bit unsigned integer, 32-bit floating-point and 32-bit RGB color.
File Formats: Open and save all supported data types as TIFF (uncompressed) or as raw data. Open and save GIF, JPEG and ASCII. Open BMP, DICOM and FITS. Open GIFs, JPEGs and raw data using a URL.
Speed: ImageJ is the world's fastest pure Java image processing program. It can filter a 2048x2048 image in 0.5 seconds. That's over 8 million pixels per second!
Plugins: Extend ImageJ by developing plugins using ImageJ's built in command recorder, editor and Java compiler. Many example plugins are provided.
Toolkit: Use ImageJ as a image processing toolkit (class library) to develop new applets and applications.
Image display: Tools are provided for zooming (1:32 to 32:1) and scrolling images. All analysis and processing functions work at any magnification factor.
Regions of Interest: Create rectangular, elliptical or irregular regions of interest (ROIs). Draw, fill, clear, filter or measure ROIs. Transfer an ROI to another image.
Image Enhancement: Supports smoothing, sharpening, edge detection, median filtering and thresholding on both 8-bit grayscale and RGB color images. Interactively adjust brightness and contrast of 8, 16 and 32-bit images.
Geometric Operations: Crop, scale, resize and rotate. Flip vertically or horizontally. Analysis: Measure area, mean, standard deviation, min and max of ROI or entire image. Measure lengths and angles. Use real world measurement units such as millimeters. Calibrate using density standards. Generate histograms and profile plots.
Editing: Cut, copy or paste images or selections. Paste using AND, OR, XOR or "Blend" modes. Add text, arrows, rectangles, ellipses or polygons to images.
Color Processing: Split a 32-bit color image into RGB or HSV components. Merge 8-bit components into a color image. Convert an RGB image to 8-bit indexed color. Apply pseudo-color palettes to grayscale images.
Stacks: Display a "stack" of related images in a single window. Process an entire stack using a single command. Open a folder of images as a stack. Save stacks as multi-image TIFF files.

JTides

Description:

«JTides is an accurate, easy-to-use tide and current prediction program. Predicts tides and currents using a large database of US and world-wide locations (over 2000). It graphs its predictions in many ways. Many locations can be graphed at the same time. You can print a calendar of tidal events. You may also print prediction charts or export application-portable databases of any size.»

This is a Java program able to run in virtually any OS. If you don't have it already you will need to download/install Sun's Java Runtime Environment (free).

This the generic Java version. A specific Java version for Windows is also available.

Mars24

Description:

Mars24 is a cross-platform Java application and applet which displays a Mars "sunclock", a graphical representation of Mars showing the current sun- and nightsides of Mars, along with a numerical readout of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle for a given location on Mars.

Note: Mars24 requires Java 1.3.1 or better.

Yale Observatory iMAge Manipulation Application

Description:

The Yale Observatory iMAge Manipulation Application (yomama) is the a java tool for fits image manipulation and viewing. It was developed under a grant entitled "Development of a Web-Based Image Analysis Package for Astronomical Data".

yomama does not require any sort of advanced scripting knowledge for its use. Written completely in Java, is platform independent and as such can be run by beginnesr or experts alike, no matter what kind of computer they own.

Note: the yomama application requires the user to have a Java Runtime Envrionment (JRE) installed (free)

Where is M13?

Description:

This free Java application is designed to help us break out of our habitual way of perceiving the night sky as two dimensional. It does this by displaying the common Messier objects in their three dimensional positions within or around the Milky Way.

Simulum

Description:

This project deals with different simulations of star movements and their visualizations. At first we look at the projection and accumulation of star brightness. In actually doing this we have to distribute stars among a three dimensional figure. To get a nice effect we combine the photographic image production with a moving view point. So we get the visual impression of flying through a star field.

Secondly we will study different algorithms of particle movements and clustering. The primary approach will use a combination of Newton's gravitational law, energy and impulse conservation.

At all these stages an highly dynamic view of the processes could be produced and will lead at least to interesting screen savers...
