Abstract
The application relates to an image synthesis method and device, computer equipment and a storage medium. The method comprises the following steps: performing projection processing on a plurality of to-be-synthesized tomographic images to obtain a first image corresponding to the plurality of to-be-synthesized tomographic images and a second image corresponding to the plurality of to-be-synthesized tomographic images; performing filtering processing on the first image and the second image respectively to obtain a low-frequency component image corresponding to the plurality of to-be-synthesized tomographic images and a high-frequency component image corresponding to the plurality of to-be-synthesized tomographic images; and obtaining a synthesis image corresponding to the plurality of to-be-synthesized tomographic images according to the low-frequency component image and the high-frequency component image. The method can improve the image synthesis efficiency.
