Hi my name is Maria and it is my first time here,

I need your help or advice.

I have to remove periodic noise from image.

I think i did it well by converting input image to frequence space and removing noises peaks (except DC). After it i have converted back the image and saw the output ( "clean image"). The output image is far from to be clean. I have attached fft of input image, fft of output image (after i have removed noises peaks) and the output image.

Could you,please, help me to find and correct my mistake.

Thank you!
