Assignee: KONINKLIJKE PHILIPS N.V.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A system for annotation of image data, the system comprising:
an input interface configured to access the image data to be annotated;
a user interface subsystem comprising:
a user input interface configured to receive user input data from a user input device operable by a user;
a display output interface configured to provide display data to a display to visualize output of the system;

a processor configured to, using the user interface subsystem, establish a user interface which enables the user to iteratively annotate the image data, wherein an iteration of said iterative annotation comprises:
the processor generating labels for a current image data part based on user-verified labels of a previous image data part;
via the user interface, enabling the user to verify and correct said generated labels to obtain user-verified labels for the current image data part;
wherein the processor is further configured to:
generate the labels for the current image data part by combining, by weighting, respective outputs of:
a label propagation algorithm which propagates the user-verified labels of the previous image data part to the current image data part, and
a machine-learned classifier for labeling of image data, wherein the machine-learned classifier is trained on user-verified labels and image data and applied to image data of the current image data part; and

retrain the machine-learned classifier using the user-verified labels and the image data of the current image data part to obtain a retrained machine-learned classifier.
