Abstract
An image grid line removing method is used for removing grid lines of an image and includes a Fourier transform step, a Gaussian-like masking step and an inverse Fourier transform step. The Fourier transform step is for providing a Fourier transform to process the image to generate a frequency domain image. The Gaussian-like masking step is for providing a Gaussian-like masking model to process the frequency domain image to generate a frequency domain masked image. The inverse Fourier transform step is for providing an inverse Fourier transform to process the frequency domain masked image to generate a grid line removing image.
