Itk image direction
WebHere is a simple python script that reads an image, applies a median image filter (radius of 2 pixels), and writes the resulting image in a file. #!/usr/bin/env python3 import itk import sys input_filename = sys.argv[1] output_filename = sys.argv[2] image = itk.imread(input_filename) median = itk.median_image_filter(image, radius=2) … Web17 nov. 2024 · This seems to be some incompatibility between NIFTI and ITK orientation definitions, but I can’t work it out. I have a test dataset with images acquired in axial, sagittal and coronal orientations. The Bruker header claims the orientation of the axial image is: 1 0 0 0 1 0 0 0 1. ITK saves this as a NIFTI with.
