#### Open and Shut [Equation of the Week]

For a discipline that relies so heavily on images, it is rather surprising how little use astronomy makes of the vast body of work on image analysis carried out by mathematicians and computer scientists. Mathematical morphology, for example, can be extremely useful in enhancing, recognizing, and extracting useful information from densely packed astronomical

images.

The building blocks of mathematical morphology are two operators, **Erode[I|Y]** and **Dilate[I|Y]**, Continue reading ‘Open and Shut [Equation of the Week]’ »
