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.
Archipel is a multithreading framework for Java. Threads working together can be seen as a graph in which each thread is a node. That's exactly what Archipel does. The aim is to make multithreading easier. Simply define your data exchange structures and write the business code for each of your threads, and Archipel handles the rest.
