METHOD AND A SYSTEM FOR IMAGE ANNOTATION
First Claim
1. An image annotation system for annotation of images, comprising:
- an image parser to parse images retrieved from an image database or provided by an image acquisition apparatus and to segment each image into image regions, each segmented image region being annotated automatically with annotation data and stored in an annotation database; and
at least one user terminal to load at least one selected image from said image database and to retrieve corresponding annotation data of all segmented image regions of said at least one selected image from said annotation database for further annotation of said at least one selected image.

Abstract
A method and a system are disclosed for image annotation of images, in particular two- and three-dimensional medical images. In at least one embodiment, the image annotation system includes an image parser which parses images retrieved from an image database or provided by an image acquisition apparatus and segments each image into image regions. The image can be provided by any kind of image acquisition apparatus such as a digital camera an x-ray apparatus, a computer tomograph or a magnetic resonance scanning apparatus. Each segmented image regions is annotated automatically with annotation data and stored in an annotation database. In at least one embodiment, the system includes at least one user terminal which loads at least one selected image from said image database and retrieved the corresponding annotation data of all segmented image regions of said image from said annotation database for further annotation of the image. The image annotation system, in at least one embodiment, allows for a more efficient and more reliable annotation of images which can be further processed to generate automatically reports for examples of patients in a hospital. The image annotation method and system according to at least one embodiment of the invention, can be used in a wide range of applications in particular of annotation of medical images but also in security systems as well as in the developments of prototypes of complex apparatuses such as automobiles.
