Today is July 21, 2011 -- exactly 5 weeks after I put up this blog... It was fun writing notes and nerdy stuff here knowing the fact that anybody, anywhere around the globe, can actually reach and read this blog. Amazing huh!
Anyway, going back to what this post really is about, I will show you how to enhance an image by removing or improving some parts in the frequency domain. To be able to follow the concepts I will use in this post, you must have some background in using Fourier Transform, if not, you can visit first my previous posts here and here.
The basic idea of this post is that whenever we have an image with repetitive patterns which are not necessary, we can get its Fourier Transform. By doing so, we are now in the frequency domain so we can create a filter that will remove frequencies pertaining to the unwanted patterns. And viola! The unwanted patterns are gone!
