The way you press a button first time can tell your attitude

If you press it very hard during very first try, it means you are blunt
and negative minded.
If you press it very gently in your first try, it means you are too soft
natured (very humble) and timid.
If you press it with right pressure in your first try, it means you are
practical or positive minded.

octave matlab code for multiple thresholding an image using histogram peaks

The following code converts an image histogram into finitely sparse histogram by using multiple thresholds that appear in histogram as peaks.

Input image in tif format:



code begins here:
