MATLAB: How to remove objects from a gray scale image in frequency domain

Question

I want to remove some objects of a gray scale image in frequency domain. I am transforming a gray scale image into frequency domain from spatial domain using fft2() and then i am doing fftshift() to shift zero frequency component to center of spectrum. I don't know i am going into right way or wrong? After doing fftshift() i am having a totally gray image with some unclear dotted center frequency component. I want to remove vertical line of that spectrum.

Sample image have some chop sticks and knives. I want to remove those chop sticks. I attached sample image and experimental image.

Here is my code:

 if true
            img = imread('sample.png');
            figure,imshow(img,'InitialMagnification','fit');
            imgB = im2bw(img,0.2);                                                      
            figure,imshow(imgB,[],'InitialMagnification','fit');
            imgF = fftshift(fft2(imgB));
            figure, imshow(imgF,[],'InitialMagnification','fit'); 
 end

I need some guideline to remove those chopsticks using frequency domain.

Answer 1

You did not attach the images. But anyway, you cannot remove chopsticks and knives by filtering in the Fourier domain. Not sure why you thought you could.
