Morphological treatment of the spot masks on a frame after analysis of the counts along the pixel lines. (a) Pixel intensity in color with the boundaries of the originally selected pixel clusters in black. (b) Boundaries of the originally selected pixel clusters in grey, pixels remaining in the mask after erosion in blue and pixels added by two successive dilations in orange. The resulting mask of reflections after morphological operations is the union of orange and blue pixels. From Kalinowski et al. (2012). |
