WebFor observations in the critical region below the optimal threshold, the function changes the labels so that the fairness constraints hold for the reference and nonreference groups. By default, when you use the SPD bias metric, the function tries to find a score threshold such that the SPD value for the nonreference group is in the range [–0.05,0.05]. WebThe graythresh function in MATLAB is used to determine the threshold level for a grayscale image, but it cannot be used directly on an indexed image. To use graythresh on an indexed image, you need to first convert the indexed image to a grayscale image. Here's an example of how to use graythresh on an indexed image in MATLAB:
WebBy default, the function imbinarize creates a binary image using a threshold obtained using Otsu’s method. This default threshold is identical to the threshold returned by graythresh. However, imbinarize only returns the … Web17 sep. 2012 · - MATLAB Answers - MATLAB Central Counting values above a threshold within a matrix.
