Improving the image quality

Hi guys

I have a problem with the image quality, when i save the result as .jpg, the quality is reduced, please help me, how can I solve it ?

Which function are you using? Are you saving an image or a figure() window?

I use saveas(gcf,'filename.jpg') in my code

If you use print() instead of saveas(), then you can give a resolution by using a '-r' option. For example,

set(gcf,'PaperPositionMode','auto')
print('YourFileName.jpg','-djpeg','-r0')  %corrected

which would print at screen resolution.

If you use print() instead of saveas(), then you can give a resolution by using a '-r' option. For example,

set(gcf,'PaperPositionMode','auto')
print('YourFileName.jpg','-djpeg','-r0')     %note correction compared to my earlier comment

which would print at screen resolution.

Try using exportgraphics().

Save the file as a PNG format file instead of JPEG to avoid lossy compression artifacts.
