Embodiment Construction
[0085] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.
[0086] The invention discloses a method for segmenting cerebral veins and blood vessels based on SWI images, which runs in the Windows 7 system environment of the Intel kernel and uses MATLAB software for image segmentation processing. Such as figure 1 Shown are three parts of blood vessel segmentation, including preprocessing part, segmentation part and optimization part. Image segmentation uses the core algorithm of blood vessel enhancement filter based on Hessian matrix for preliminary blood vessel segmentation, preprocesses and enhances the tubular structure through anisotropic filter enhancement technology, and performs post-optimization processing through the area method and Isdata threshold method to obtain accurate cerebral veins Split the image.
[0087] Such as figure 2 Shown, a kind of cerebral vein blood vessel segmentation method ba...
