How to fuse or overlay multiple masks of clustering results onto the original image in a for loop

Something like the final image here but looped for an unknown number of groupings. Iterative imfuse or imoverlay is diminishing the intensity of the colors too much beyond 3 groups and it makes looping impossible when the number of groups is unknown. I was thinking automated binary mask creation for the identified particles in each group but I can't figure out the code to do that.

yes，sir

may be use bwlabel and label2rgb to make the maks label to rgb image

then，use imshow handle to set the AlphaData，such as

close all;
clear all;
clc;
im=imread('rice.png');
bw=imbinarize(im,'adaptive');
[L,~] = bwlabel(bw);
Lrgb = label2rgb(L, 'jet', 'w', 'shuffle');
figure; imshow(im, [])
hold on
himage = imshow(Lrgb);
set(himage, 'AlphaData', 0.3);
