Image Editors


ImageJ
ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and 'raw'. It supports 'stacks', a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations.

Hugin
With Hugin you can assemble a mosaic of photographs into a complete immersive panorama, stitch any series of overlapping pictures and much more. The first step to making a great panorama or photomosaic is to start with a number of photographs. Hugin allows images to be added in any orientation, in any direction. However, you may find it easier to give Hugin a few approximate hints about where each image belongs. You can specify a certain image to be your guidepost, or anchor. The anchor image will not be moved around, but all of the others will be moved to align to it. You can also specify yaw, pitch and roll orientation for each image, if you know them. Changes to these numbers will be reflected immediately on the Panorama Preview.

iTag
iTag allows users to define up to 9 different categories and name them accordingly. In addition, 4 modifiers are available to further increase the options during a tagging session. Users are able to load a series of Images into a session and add tags on objects on these images within previously defined categories and modifiers. Upon ending the session, result files are produced including (if provided by the EXIF data) the GPS information for each Picture, the number of objects in each category and a detailed result file that describes each individual object.

JPEG Lossless Rotator
Have you ever thought that when you rotate a JPEG photo you lose its quality? All people usually make photos with different shot orientaton, and some photos need to be rotated. When you rotate a JPEG photo, most image editors decode the photo, rotate the bitmap and then reencode it back to JPEG. This process slightly decreases the final image quality. Unlike other tools, JPEG Lossless Rotator does not recode your image but will perform a special lossless block transformation. As a result, a rotated image has exactly the same quality as the original.
