Image annotation tool with bounding boxes

I wrote an tool that facilitates the annotation of objects in images with bounding boxes. It has been written in Qt, it therefore is portable to different platforms.

Features:

• annotation of objects with bounding boxes
• support for easily modifying, copying and pasting bounding boxes
• zoom in/out
• per object, freely chosen "fix points" can mark additional points on objects (these can be used to align annotated objects more accurately)
• the rotation of an object can be annotated (with fix points)
• each object can have freely chosen properties (numbers, text)
• the tool can even by used to visualize detection results (ordered by a score value)
• a subset of visible objects in an image can be chosen
• support for properties of images (numbers, text)
• selection of objects by filtering over properties
• alignment and extraction of selected objects
• generation of random samples per annotated object by applying various distortion methods

Download: as source code such that you may build it yourself on your platform (the README file explains how to do that and gives also some information about the internal format).

In the Image Annotation Tool, you have a menu help->shortcuts that gives you a short list of the most common short cuts. Otherwise, keep the cursor for a longer while over buttons or text fields (in the extract dialog) to get some more hints and information. In case I missed something or you have a question, drop me a line.

Here you see a screenshot under Linux:
