Dear sir,
I use simple linear iterative clustering algorithm.the program is attached below
A = imread('capture1.jpg');
[L,N] = superpixels(A,100);
figure
BW = boundarymask(L);
imshow(imoverlay(A,BW,'cyan'),'InitialMagnification',67)

I = imread('capture1.jpg');
[L,N] = superpixels(I,100);
figure
BW = boundarymask(L);
imshow(imoverlay(I,BW,'cyan'),'InitialMagnification',67)
% Area of each patch
A = zeros(N,1) ;
for i = 1:N
A(i) = nnz(L==i) ; % area in pixels
end

dear sir,
How know which patch area is calculated,how the patches are numbered?
Also if the individual patch area calculated separately.The figures are attached below.How the area calculated?
