Claim 12:
13. A computer-implemented method for annotation of image data, the method comprising:
accessing the image data to be annotated;
using a user interface, enabling a user to iteratively annotate the image data, wherein an iteration of said iterative annotation comprises:
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 labels for the current image data part are generated 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

retraining 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.
