# what's the sequence of &lt;ofxCvBlob&gt; in ofxCvContourFinder?

Hi all~
ofxCvContourFinder has a variable: vector blobs. i’m wondering is there a certain order for these blobs? i.e., the blobs are indexed sequencely following a kind of top left to buttom right order (maybe based on their centroid)? or these blobs are just indexed randomly?

quickly – they come in the order of size (biggest to smallest). now that you ask, it might make sense, in the future, to allow for different sorting options. for now, that’s how it works.

take care!
