I am working on astronomical image processing plug-in for Opticks.
In this week, I begin to implement the de-convolution algorithm for image
De-convolution attempts to restore an image that has been degraded to its
original pre-degraded condition. Successful de-convolution methods work
using a constrained iterative process of image estimation and correction.
Rather than attempt to solve the inverse convolution problem in a single
step, image estimation relies on a series of small steps successive that
eventually converge on a best estimate of the original image.
Two types of de-convolution methods will be implemented. The first one is
Van Cittert method that uses additive correction. Another one is the
Richardson-Lucy method. It is based on the maximum likelihood approach and uses
a multiplicative correction factor.
The details of the report can be found at:
Next week I will finish the implementation of the de-convolution method for
