Remove small spurs, but keep the longest line

[E Hansen]

Hi, 

I need to remove the small spurs on this line, but I have to keep the longest line, because I need this for tracking. I tried using imaq extract curves, but I know it is not designed for binary pictures.

Anyone  got an idea to track the longest line or how I can remove the small spurs without deleting pixels from the long line?

Thanks, Esben.

Try eroding with customizing the kernel elements. And dilate when you see the spur getting invisible.

I need it to be an automated system, and I tried eroding/dilating, also using hit-miss, but it removes pixels on the end of the long line...
