A method for normalization and enhancement of MRI brain images by multiscale filtering

摘要

Problem to be solved: to provide a three-dimensional MRI image processing method of voxel including brain material.Multiscale filtering is used to normalize the voxel intensity in MRI images.The image generated by the multi scale filter applied to the low MRI image is compared with the original image, and the Roma abnormality (i.e., intensity change) is corrected based on the comparison.In one approach, the intensity of the image is increased for the dark voxel rather than the multiscale filtered version, and the brightest voxel is less than the multiscale filtered version.In other embodiments, further features are provided based on a multiscale gradient, which may be used in combination with other approaches to segment MRI images.A positive gradient voxel may represent the brain gray that is bound by the brain white matter, and the negative gradient voxel may represent the brain white matter that is bound by the brain gray matter.Diagram
