You can use functions like conv2, deconvreg, deconvwnr, deconvlucy, deconvblind.

To save the images, use imwrite to save them in PNG format on disk.

ty sir, so PNG is more relieble dan JPG right?

If you want to preserve image quality, particularly around edges and fine details, do not use JPG. PNG is lossless and widely supported.

What @DGM is true. Where JPG also shows its horribleness is in large smooth gradients. Think of how many blue sky and sunset photos you've seen with bad posterization effects (false edges).
