Software Patch implements a method based on sectioning approach in deconvolution of space-variant astronomical images.
Software Patch implements a method based on sectioning approach in deconvolution of space-variant astronomical images. The starting point is a mosaic of PSFs, provided by the users, and the input image. The image is partitioned in non-overlapping regions such that each PSF can be considered space-invariant on them.
The subsequent step consists in applying a deconvolution method modified for taking into account correction of boundary effect. Both the well-known Richardson-Lucy and a fast method called Scaled Gradient Projection, SGP, are available.
Finally, the output object is obtained as a mosaic of the reconstructed regions.
