Abstract

The embodiment of the invention discloses an image fusion method for a medical fluorescence imaging system in the technical field of medical fluorescence imaging, and the method comprises the following steps: S1, carrying out the saliency region detection of a visible light image, obtaining a saliency map Svis, and carrying out the saliency region detection of a fluorescence image, and obtaining asaliency map Sflu; S2, calculating a fusion weight of the visible light saliency map and the infrared light saliency map; and S3, performing image fusion on the fluorescence image and the visible light image, and outputting a fusion image result. According to the method, the fusion weight is calculated by adopting the saliency map, and pseudo-color image fusion is carried out in the RGB color space, so that fluorescent region features can be highlighted, texture features of a fluorescent stimulated region can be enhanced, and the fused image is more natural and comfortable in impression; andthe fused image can effectively reserve key information in the image, enhance fluorescence characteristics in the fused image and highlight texture information of a fluorescence region.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical fluorescence imaging, in particular to an image fusion method of a medical fluorescence imaging system. Background technique [0002] With the continuous development of molecular imaging technology, near-infrared fluorescence (NIRF) imaging technology shows great application potential in the field of surgery. With the continuous maturity and development of technology, it has been gradually applied in many surgical fields. In particular, near-infrared fluorescence imaging technology based on indocyanine green ICG has important applications in many branches of surgery. The principle of near-infrared fluorescence imaging is to irradiate the tissue of interest with an excitation light source (750-800nm), the fluorescent agent is excited to emit near-infrared light with a longer wavelength (greater than 800nm), and the fluorescence imaging of the surgical area is obtained by coll...
