hi, this is my code for: -converting the rgb image to hsv image -obtain the blob -obtain the eigen values
clear all;
i=imread('A.jpg');
x =imresize(i,[100 100]);
j=rgb2hsv(x);
s=j(:,:,2);
sthres=s>0.2;
sthres=imfill(sthres,'holes');
%figure(1), imshow(sthres);
CC=bwconncomp(sthres);
numPixels = cellfun(@numel,CC.PixelIdxList);
[biggest,idx] = max(numPixels);
sthres(CC.PixelIdxList{idx}) = 1;
%figure(1), imshow(sthres);
M=mean2(sthres);
C=(sthres-M)*(sthres-M)';
lamda=eig(C);
[V,D] = eig(C);
i m not sure if my code is correct. Could someone please tell me how to obtain the eigen vectors. V,D,W]=eig(__) is showing error. please let me know if my code is wrong.
