MRML for KDE

MRML for KDE is a KDE MRML client which offers integration of content-based queries into Konqueror/KDE. It consists of a KPart (which could be embedded into Konqueror for example) and a kio-slave for communication with the MRML server. You can right-click on an image and choose "Search for similar images..." in the context-menu, which will perform a query on a server and present you a thumbnail view of the results. You can also refine queries by giving relevance feedback.
