(A) Segmentation accuracies for the 5 simulated density maps shown in Figure 6. (B) Segmentation accuracies for simulated density maps of GroEL+GroES and Ribosome. Accuracies obtained with the grouping by scale-space filtering method are plotted with blue squares, accuracies obtained with the smoothing and sharpening method [31] are shown with green dots, and maximum accuracies attainable by grouping watershed regions are plotted with red asterisks. The same parameters were used for the two smoothing-based methods; the grouping method presented in this paper achieves slightly better segmentation accuracies.
