How to remove the shadow of the fixed grid?

The invention discloses a method for removing grid shadows of X-ray images. The original X-ray image is subjected to filtering processing and edge detection to obtain a mixed image containing grid shadows and tissue edges, and then straight line screening is performed. After obtaining the preliminary grid shadow image containing the preset grid shadow lines, the non-filter grid shadow lines are removed to obtain the intermediate grid shadow image containing only the grid shadow lines, and the correction curve is constructed. function to correct the intensity of the intermediate grid shadow image to obtain the final grid shadow image, and finally subtract the final grid shadow image from the original X-ray image to obtain the image after removing the grid shadow. The invention also discloses a mobile terminal and a computer-readable storage medium. The invention effectively prevents the artificially introduced artifacts, and greatly improves the efficiency of removing wire grid shadows.
