I have 360x360 image I want to remove lines in it

half portion on it has noisy lines I am working on MATLAB

I tried median filter, bilateral filter but not working how to denoise this image and remove lines?

This has periodic lines

I used this :

CODE CREDITS : IMAGE ANALYST

figure(2);

%-----------------------------------------------------------------------------------------------------------------------------------
rgbImage = maxarray;
[rows, columns, numberOfColorChannels] = size(rgbImage);
% Display the test image full size.
subplot(2, 2, 1);
imshow(rgbImage,[]);
axis('on', 'image');
drawnow;
%hp = impixelinfo(); % Set up status line to see values when you mouse over the image.
b=max(rgbImage,[],3);
% How about you sum the image vertically to get a horizontal profile?  
horizontalProfile = mean(b(:, :));
subplot(2, 2, [2, 4]);
figure(2);plot(horizontalProfile, 'b-');
grid on;
bottomEnvelope = movmin(horizontalProfile, 20);
upperEnvelope = movmax(horizontalProfile, 20);
deltaGL = mean(upperEnvelope(150:250) - bottomEnvelope(150:250))
hold on;
plot(bottomEnvelope, 'r-', 'LineWidth', 2);
plot(upperEnvelope, 'r-', 'LineWidth', 2);
midline = (bottomEnvelope + upperEnvelope) / 2;
plot(midline, 'm-', 'LineWidth', 2);
% Determine what rows are above the midline. 
% Those are the columns that are 50 gray levels brighter.
columnsToDim = horizontalProfile > midline;
% Darken those columns in each color channel.
rgbImage(:, columnsToDim) = rgbImage(:, columnsToDim) - double(deltaGL);
% Reconstruct output image.
subplot(2, 2, 3);
imshow(rgbImage, []);
caption = sprintf('Corrected Image where %d was subtracted from the stripes.', deltaGL);
title(caption, 'FontSize', fontSize, 'Interpreter', 'None');
drawnow;
