Multi-source medical image fusion method and system based on domain transformation edge-preserving filter

The invention discloses a multi-source medical image fusion method and system based on a domain transformation edge-preserving filter, and the method comprises the following steps: inputting a multi-source medical image into the domain transformation edge-preserving filter for filtering processing, and obtaining a smooth component and a structure component of the multi-source medical image; fusing the corresponding smooth component and the structure component to obtain a fused smooth component fusion image and a fused structure component fusion image; and performing inverse transformation on the fused smooth component fusion image and the structure component fusion image to obtain a fusion image of the multi-source medical image. According to the method, the difference information between the images of different modalities can be effectively fused and displayed in a concentrated manner, a doctor can be assisted to better know the physical condition of a patient and accurately judge the diseased area of the bo
