ImageJ

ImageJ is a Windows application for image processing and comparison. It uses open source code and supports third-party plug-ins to extend its functionality. The program is actively used for scientific purposes. There is a built-in function for editing images and making density histograms. Built-in algorithms allow making complex calculations, which allows the program to be used in many areas.

Viewing and analyzing

After opening the application, you need to select the source file. All major types of image files are supported, including FITS and RAW. Batch mode is provided - you can load and process a set of files. The utility allows you to perform the following operations:

• sharpening;
• measuring angles and distances;
• contrast correction;
• logical and arithmetic operations;
• harmonic analysis;
• boundary detection;
• smoothing.

It is possible to perform geometric transformations of different types, including scaling and rotation. During batch processing the number of files is limited only by RAM parameters.

Scenarios

The application supports working with scripts, which allows you to automate similar actions. The presence of an open API makes it possible to integrate third-party plugins. This can be used to extend the basic functionality. You can integrate both your own modules and use the work of other users. There is a help section, which will allow users with different levels of training to quickly get acquainted with the functionality. There is a description of interface elements, a list of available elements, modes of operation and much more. Additional materials are provided.

Features

• a set of tools for analyzing and editing images;
• function for determining the density of pixels in a certain area;
• histogram creation;
• the program is distributed free of charge.
