    <p>I am trying to find centroid of objects. I have already implemented connected components labeling and I have developed following code for centroid, it does give result but does not gives correct result: I have following output matrix i.e matrix_img:</p> <pre><code> 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 0 0 2 2 2 2 0 0 0 0 0 1 1 1 1 1 1 0 2 2 2 2 0 0 0 0 1 1 1 1 1 1 1 1 2 2 2 2 0 0 0 0 1 1 1 1 1 1 1 1 2 2 2 2 0 0 0 0 1 1 1 1 1 1 1 1 2 2 2 2 0 0 0 0 0 1 1 1 1 1 1 0 2 2 2 2 0 0 0 0 0 0 1 1 1 1 0 0 2 2 2 2 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 0 0 5 5 5 0 0 0 0 0 0 0 2 2 2 2 0 0 5 5 5 0 0 0 0 0 0 0 2 2 2 2 0 0 5 5 5 0 0 0 0 0 0 0 2 2 2 2 0 0 0 0 0 0 0 0 0 0 0 0 </code></pre> <p>and following is the code</p> <pre><code>n= max(max(matrix_img)); for k=1:n a(k)=length(find(matrix_img==k)); sx(k)=0; sy(k)=0; cx=0; cy=0; for i=1:1:r for j=1:1:c if(matrix_img(i,j)==k) sx(k)=sx(k)+i; sy(k)=sy(k)+j; cx=sx(k)/a(k); cy=sy(k)/a(k); end end end fprintf('Centroid of Object %d is %d and %d \n', k, cx, cy); end </code></pre> <p>It gives result like :</p> <pre><code>Centroid of Object 1 is 7 and 1.250000e+001 Centroid of Object 2 is 1.050000e+001 and 2.500000e+000 Centroid of Object 3 is 0 and 0 Centroid of Object 4 is 0 and 0 Centroid of Object 5 is 14 and 8 </code></pre> <p>Object 5 result is correct, object 2 is completely wrong and object 1 is partially wrong.. what shall I do?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
