Marvin is an extensible image processing framework for Java. It provides features to manipulate images, to manipulate captured video frames, and to process images with multi-threading. Its features can be extended via plug-ins. Plug-ins can be integrated with the graphical user interface, and their plug-in performance can be analyzed. Every image processing algorithm is developed as a plug-in that can be plugged into the MarvinEditor, an image manipulation program that uses plug-ins developed using Marvin, or into third-party applications. Currently there are 55 plug-ins available.
Thumbnailator is a thumbnail generation library with a fluent interface for Java. It simplifies the process of producing thumbnails from existing image files and image objects by providing an API which allows for fine tuning of thumbnail generation, while keeping the amount of code that needs to be written to a minimum.
AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. It supports the following features: tunable webcam sampling; image stacking (averaging, additive etc.); pre and post-capture gamma (brightness) and contrast correction; dark-shot CCD calibration (subtractive); and an internal 16-bit grey-scale format for optimal resolution.
Applications that use images usually have requirements for the size of these images. To be able to use an image, users have to cut out the area they want and then resize it to the required size. This is a cumbersome and time-consuming process for most users. With the Image Cutout Component, you can add functionality to crop and resize images to your application, so your users can focus on their task: selecting the area of interest. You tell the component what the desired size is, and the component makes sure the area the user selects has the correct aspect ratio. When the user indicates he has finished selecting the area, the component will crop and resize the image.
Fiji is an image processing package. It can be described as a distribution of ImageJ together with Java, Java 3D, and a lot of plugins organized into a coherent menu structure. Fiji compares to ImageJ as Ubuntu compares to Linux. The main focus of Fiji is to assist research in life sciences. For users, Fiji is easy to install and has an automatic update function, bundles a lot of plugins and offers comprehensive documentation. Developers may access the source code of all internals, libraries, and plugins, which eases the development and scripting of plugins.
