Two vectors are pointing similar directions if one minus their dot product is less than a threshold. … Threshold an image using the Otsu Threshold. This filter creates a binary thresholded image that separates an image into foreground and background components. The filter computes the threshold using the OtsuThresholdCalculator and applies that threshold to the input image using the BinaryThresholdImageFilter . Author Richard Beare Gaetan Lehmann.

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 ...
