- First, read the NASA supernova image (https://www.nasa.gov/image-feature/goddard/2019/hubble-sets-sights-on-an-explosive-galaxy) and convert the image into a binary one. Negate the binary image:
supernova_gray = sitk.ReadImage('images/supernova.jpg', sitk.sitkFloat32)supernova_bin = sitk.BinaryNotImageFilter().Execute(sitk.OtsuThresholdImageFilter() .Execute(supernova_gray))
- Instantiate the SimpleITK filter objects corresponding to the opening and closing morphological filters. Set the SE as a disk of radius 3. First, apply the opening filter followed ...
