Cleaning up blurry images using Matlab

Question

I want to take an image of blurry cylindrical objects and get rid of the blur, basically sharpen the image. How do I do that in Matlab?

Answer 1

See the "sharpening" section in http://www.aquaphoenix.com/lecture/matlab10/page3.html.

Answer 2

You can do it with filters.

See here, section 10.2.4 here: http://www.aquaphoenix.com/lecture/matlab10/page3.html

Answer 3

In addition to all the good answers by others: for the very very simple inputs, you can simply threshold the image if you just need the boundary of those cylinders.
