Results of segmentation example. The spot intensities estimated from the simulated images with the fixed circle (first row), the histogram segmentation (second row), and the seeded region growing (third row) segmentation algorithms are plotted against the input data (reference). The plots are from the first channel of the test images: (a) intensities for the high quality image given by the three segmentation algorithms, (b) intensity plots for image with noise and errors, (c) plots for image with disturbing noise and artefacts.
