Web15 aug. 2024 · I applied k-means algorithm for segmenting images. I used built in k-means function. It works properly but I want to know the threshold value that converts it to binary images in k-means method. For example, we can get threshold value by using built in function in MATLAB: WebThe index where the max occurs is the. % optimum threshold. There may be several max values. If so, average. % them to obtain the final threshold. maxSigsq = max (sigSquared); T = mean (find (sigSquared == maxSigsq)); % Normalized to range [0,1]. 1 is subtracted because MATLAB indexing.
