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?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Astronomical Image Deconvolution

Module by: Brenton Loeffelman. E-mail the author

Summary: Rice University ELEC 301 project looking at the use of Weiner filters in the deconvolution of multiple noisy astronomical images into a single, clean image.

In the realm of image processing, one of the problems that is frequently encountered is the problem of deconvolution; given a noisy, blurred signal, how do we estimate and remove the noise and distortion and thereby obtain a clean copy of the original signal? The processes used given a single input to the deconvolution (single-input single-output deconvolution or SISO-D) are well studied, and a variety of techniques have been developed to cope with this problem. However, the realm of multi-input single-output deconvolution (MISO-D) is still being explored, and new strategies are being developed for optimal deconvolution given multiple inputs. Our goal is to use a basic SISO-D technique, the Weiner filter, applied to multi-input data to obtain a clean copy of the orignal signal for a set of astronomical images of the globular cluster Messier object 3, and to show the overall strategy used in current MISO-D image processing techniques.
