Annotation Tool

Annotation Tool is a Matlab-based image annotation tool.

Use Annotation Tool to label objects in your images. Annotated objects are represented as image region boundaries assigned with object category labels. Image annotation is saved in the form of a XML file. See documentation below for details.



The code has been tested on several Windows and Linux machines and different versions of the Matlab package. Suggestions and bug-reports are welcome.
