BLOB DETECTION ALGORITHM.....VIDEO

[superchiku]

hey guys thanks to u ppl i was able to develop this simple blob detection algorithm which is fairly accurate and can serve any general purpose....enjoy the video and the song

cheerio...i jst improvedthe algo..the accuracy is better now...

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?

[superchiku]

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...

[offy]

Is it hooked up to a webcam?

[superchiku]

ya video processing...

[offy]

Can I have the code so I can try it out?

[superchiku]

its in opencv sure u can have t ..if u have yahoo messenger then give me ur id ..ill addd  and send u

hi can i have to code as well..
 
i manage to try out the sample in opencv which detect reb image. i wada to learn to add blob and track it.

please sent to [email protected]

thanks..

[superchiku]

i detected sum bugs with the code...i need to add sum extra filtering to it...if u still need it then ill give u

[luiyl]

yup.. thanks..

[superchiku]

ok ill send the code to ur email...correct the bugs.. .

[luiyl]

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;
       }
   }
