How to prune leafs on edge image ?

Hello,

How do i can the outliers on the image edge like you find an example below ? You can find the image below. So far I tried watershed. I divides the image in corrent areas but then i can only use area filter which i dont want to because this outliers can be really long sometimes and if I increase area then it also cuts big zones.

thanks in advance
