Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Astronomical Image Deconvolution: Final Result

Module by: Brenton Loeffelman. E-mail the author

Summary: Final results for astronomical image processing using Weiner filtering and weighted averaging.

The final estimation of the original object can be seen below; the black border on the left and bottom sides of the image was created by the image registration process. As shown in the image and below, the noise level of the image was greatly reduced. Also, the star points appear much more focused, and several stars that were previously very dim now appear more clearly in the processed image.
