WebThresholding merupakan salah satu metode segmentasi citra di mana prosesnya didasarkan pada perbedaan derajat keabuan citra. Dalam proses ini dibutuhkan suatu nilai batas yang disebut dengan nilai threshold. WebOct 24, 2024 · The idea is to use two thresholds, one that is more selective and one that is less selective, and then let the more selective result "grow" by adding touching pixels from the less selective result. Here's a simple, contrived example to illustrate what I mean. A = …

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:
WebJun 22, 2024 · I would use the findpeaks function, a very useful function I like to use for finding peaks of particular width without going through a loop.
