Abstract
This invention provides an image synthesis method, apparatus, device, and medium for X-ray security inspection. It relates to the field of image processing technology and addresses the visual distortion problem caused by traditional linear interpolation methods in X-ray image synthesis. The method includes: acquiring a first X-ray security inspection image and n second X-ray security inspection images; n being a positive integer; sampling first transformation coefficients and n second transformation coefficients from a preset distribution; performing power-law transformations on the pixel values of the first X-ray security inspection image and the n second X-ray security inspection images based on the first transformation coefficients and the n second transformation coefficients, respectively, to obtain a first transformed image and n second transformed images; and performing a product operation on the first transformed image and the n second transformed images to generate a fused X-ray security inspection image. This method can construct X-ray security inspection image data that combines physical plausibility and visual realism.
