WebbThresholding. #. Thresholding is a technique of image segmentation. It separates a given single-channel image (or stack) into two regions: Pixels with intensity below a given threshold, also called “background” and pixels with intensity above a given threshold, “foreground”. Typically those algorithms result in binary images where ... http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/Python_html/33_Segmentation_Thresholding_Edge_Detection.html

Webb21 mars 2024 · As you are actually only interested in the head, you likely can use simple thresholding, possibly try Otsu to define the head mask: mask = sitk.OtsuThreshold (image,0,1) and provide the mask as input to the bias field correction. Don’t forget to check that the mask actually segments the head.
