Fig. 8.

Illustration of segmentations obtained by the proposed method with mono-scale feature learning (i.e., M ² EDN-S) and multi-scale feature learning (i.e., M ² EDN), respectively. The yellow circles indicate that the multi-scale feature learning strategy can effectively remove false positive detections produced by M ² EDN-S. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
