I couldn't improve images with distorted lines and stripes. I'm new to Matlab.
How can I make improvements to my horizontal and vertical planes?

Neither can anyone else, since nobody knows the context for the expression or what paper you're using.
If you want to replicate someone else's work, you might try asking the authors for supplementary material. There's no guarantee that they'll respond (or that the work was written in MATLAB), but if they do, at least they have subject familiarity.

Hi Abdulkadir,
I understand that you want to denoise the image which contains noise in the form of horizontal and vertical stripes. As per my understanding, there is no fixed solution for this. You have to try multiple image denoising techniques to remove the noises and find out which technique works best for your purpose.
Below are the few techniques that I would recommend:
1) If the stripes are periodic, convert the image to the frequency domain, filter out these peaks, and then convert the filtered image back to the spatial domain. You can refer to the following MathWorks documentation to understand more about image filtering in the fourier domain.
2) You can try using a combination of standard denoising filters like median filter using "medfilt2" function and adaptive filtering like weiner filter using "wiener2" function to remove the noise. You can refer to the following MathWorks documentation to understand more about each function.

I hope it helps.
