* Process/Smooth command, 8-bit image, 3GHz Windows PC, IE 6.0, Microsoft Java 1.1.4.
- Runs Everywhere:
- ImageJ runs on Linux, Mac OS 9, Mac OS X and Windows.
- 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, BMP and ASCII. Open DICOM, FITS and PGM.
Open TIFFs, GIFs, JPEGs and raw data using a URL.
- ImageJ is the world's fastest pure Java image processing program. It can filter a 2048x2048 image in 0.1 seconds (*). That's 40 million pixels per second!
- Automate tasks and create custom tools using macros. More than 70 example macros
are available on the ImageJ Web site
- Extend ImageJ by developing plugins using ImageJ's built in command recorder, editor and
Java compiler. Over 100 plugins are available.
- Use ImageJ as a image processing toolkit (class library) to develop
applets, servlets or 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.
- 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.
- 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.
- 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.
