WebJun 7, 2024 · The fft output of your code with this left-rolled kernel is some half-inverted and half-upright mixed image. Also, I had first done fft-based convolution without the fftshift function and it gave the same extra-blurry output as shown in the question but an inverted one (by 180 deg). So I did the fftshift part, and at least got an upright output.
