nice, very very nice. I have a few questions about it though. If there is only 2 blobs, will it only show blue and green? Does it have to be that exact color red?

yes it will show blue and green only..... actually i designed it for red blobs..but the code only needs minor modifications for blobs of any other colour...like only changing an array index value...

hi guys, i receive some error while trying to compile the above sample code, has it got to do with the initial declaration??


   int height1=hw->height;
   int width1=hw->width;


warning C4244: 'argument' : conversion from 'float' to 'int', possible loss of data


//finding centre of gravity...
   for(float i=0;i<height1;i++)
   {
      for(float j=0;j<width1;j++)
      {
       s=cvGet2D(hw,i,j);  ******** error is here******************
       if(s.val[2]>120)
       {
         xcounter++;
         ycounter++;
         xpixel+=j;
         ypixel+=i;
       }
   }
