Extracting Filaments Based on Morphology Components Analysis from Radio Astronomical Images

Figure 10

Extraction results obtained using our method. (a) Un-colored extracted filament. Noises are removed, and filament’s structures are retained. (b) Colored extracted filament. Compared to the filament in Figure 9(b), filament’s structures are more complete, especially in three marked places. (c) Contour extraction. (d) Residuals after the subtraction of the extracted filament from the original image.
