Object detection using blob.

Postby shivamkalra » Thu Jul 01, 2010 10:30 pm

Hi, someone please guide me how could I find a tip of object of rectangular shape(always in up direction). And also how to extract the blog shown below, I tried process blob by size but as you can see in picture, it does not work perfectly. It sometimes detect very small blobs. Please help.

Also please tell me what is the best way to detect the blue cap. Right now I'm using Color filter>> Gray Image>> Erosion>> Dilation>> Blob counter>> after that I'm almost lost. I'm gonna use this always in white background but I need higher precision so pleas tell the best way.


Thanks in advance.
