Segmemtation Algorithm of DTI Image Based on New Morphological Gradient Parameters
Lin Ta · Video Engineering · 2015
To solve the problem of losing detailed edge information inherent in traditional DTI image segmentationmethods, some new morphological gradient tensor parameters are proposed. Based on the tensor similaritymorphological gradients and tensor morphological anisotropic gradients, the tag based on watershed algorithm isapplied in DTI image segmentation. The human brain corpus callosum image segmentation experiments show that thisalgorithm with the TMG-l2 and TMG-RA parameters can quickly and accurately locate and segment the outline ofthe image, and the edge information of the important region is preserved.
