Results

The algorithm has been tested on 57 images and the results have been compared to the ones obtained by two human graders: As for the training set, the specialists graded the images independently, then they compared and discussed the results. The result of this procedure was considered as golden standard.

The comparison with the automatic method gave a mean sensitivity of 88.1% and a predictive value of 83.8% (2.3 FP per image). In Fig. 7.32, an example is shown.
