    <p>As requested here is my exact code where i want to calculate centroids from contour My exact code is like this 1) Taking RGB image as input 2) x=0,y=0,w=width of frame,h=height of frame.are the data passing</p> <p>void cRecursiveCentroids::ComputeCentroid(int x, int y, int w, int h, IplImage *data, bool splitOnUpDown, int level, int id, int addToId){</p> <pre><code>if (level == m_Levels-1 ) return; int Channels = data-&gt;nChannels; // Number of channels std::cout &lt;&lt; "Channels: " &lt;&lt; Channels &lt;&lt; "\n"; int xPos = 0; int yPos = 0; int nPix = 0; for (int i = x; i &lt; x+h; i++) //Tracing the contour { for (int j = y; j &lt; y+w; j++) { int pos = i * m_Wid * Channels + j; // Here may be the error i am thinking // if any data exists if (data-&gt;imageData[pos]&gt;0) { xPos += j; //std::cout &lt;&lt; "xPos: " &lt;&lt; xPos &lt;&lt; "\n"; yPos += i; // std::cout &lt;&lt; "yPos: " &lt;&lt; yPos &lt;&lt; "\n"; nPix++; } } } Check = nPix; if (nPix &gt; 0){ // Calculating Position xPos = (int)((float)xPos / (float)nPix); yPos = (int)((float)yPos / (float)nPix); int num = ( id + addToId ) &gt; 16 ? 16 : (id+addToId); m_Cent[num].posx = xPos; m_Cent[num].posy = yPos; m_Cent[num].level = level; splitOnUpDown = !splitOnUpDown; level = level+1; if (splitOnUpDown) //Recursive calling for centroids { id *= 2; ComputeCentroid(x,y,w,(yPos - y), data, splitOnUpDown, level, id, addToId); ComputeCentroid(x,yPos,w,h-(yPos-y), data, splitOnUpDown, level, id+1, addToId); } else { id *= 2; ComputeCentroid(x,y,(xPos-x),h, data, splitOnUpDown, level, id, addToId); ComputeCentroid(xPos,y,w - (xPos-x),h, data, splitOnUpDown, level, id+1, addToId); } } DrawCentroidPoints(); //Draw Centroid Points </code></pre> <p>}</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.
