ImageJ是一個基於java的公共的圖像處理軟件，它是由National Institutes of Health開發的。可運行於Microsoft Windows，Mac OS，Mac OS X，Linux，和Sharp Zaurus PDA等多種平台。其基於java的特點， 使得它編寫的程序能以applet等方式分發。



ImageJ能夠顯示，編輯，分析，處理，保存，打印8位，16位，32位的圖片， 支持TIFF, PNG, GIF, JPEG, BMP, DICOM, FITS等多種格式。ImageJ支持圖像棧功能，即在一個窗口里以多線程的形式層疊多個圖像， 并行處理。只要內存允許，ImageJ能打開任意多的圖像進行處理。除了基本的圖像操作， 比如縮放，旋轉， 扭曲， 平滑處理外，ImageJ還能進行圖片的區域和像素統計， 間距，角度計算， 能創建柱狀圖和剖面圖，進行傅里葉變換。

-ImageJ is a java-based image processing software in public, it is by the National Institutes of Health developed. Can run on Microsoft Windows, Mac OS, Mac OS X, Linux, and the Sharp Zaurus PDA and many other platforms. The characteristics of their java-based, making it able to write programs applet, etc. distributed.



ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit, 32-bit images, support for TIFF, PNG, GIF, JPEG, BMP, DICOM, FITS and many other formats. ImageJ supports image stack functions, namely, a window in the form of multi-threaded Cascading multiple images, parallel processing. As long as memory allows, ImageJ can open any number of images for processing. In addition to the basic image manipulation, such as scaling, rotation, distortion, smoothing things, ImageJ can be a picture of regional and pixel statistics, spacing, angle calculation, can create histograms and profiles, the Fourier transform.
