1-D Signal Deblurring Code Version 1.0:
- Self-contained package with examples. Best suited to users who run MATLAB.
- Unix/Linux/Solaris: Gzip compressed code (62 kb).
- Unpack gzip'ed files using "gunzip forward1d.tar.gz" followed by "tar -xvf forward1d.tar".
Then, read the README file in the unpacked directory.
- Windows: Winzipped code (107 kb).
- Unpack using winzip.
Then, read the README file in the unpacked directory.
Image Deblurring Code Version 2.0:
- Self-contained package with examples. Best suited to users who run MATLAB.
- Unix/Linux/Solaris: Gzip compressed code (495 kb).
- Unpack gzip'ed files using "gunzip forward.tar.gz" followed by "tar -xvf forward.tar".
Then, read the README file in the unpacked directory.
- Windows: Winzipped code (533 kb).
- Unpack using winzip.
Then, read the README file in the unpacked directory.
- Improvements over version 1.0: results are visually better -- contain lesser ripples.
