Yes, that is what happened. I lowered the mean. What I did not know is that in every iteration after computing the new mean and standard deviation, the output buffered is filled with zeros. So, every iteration starts with a completely blank image, not with the output of the previous iteration. This may make sense, however, it was misleading for me, I think it should be noted in the documentation.<br>

In a recent thread that I cannot find right now, someone said that Connf connected can discard already segmented pixels as iterations increase, giving certain conditions (ie: a big number of homogeneous pixels are segmented, lowering the mean and hence excluding pixels that were segmented before, if I remember correctly)<div>

The problem happens when the multiplier is below 1.0. Is it a misuse to specify such a multiplier?<br><br>I attached a sample code, and I will send the sample image in private. (0.5MB)<br><br>Thanks,<br>Miklos<br><br><div class="gmail_quote">

It should not. Are you adding as seeds an entire mask of pixels ? Can<br>
you post a minimal working example demonstrating this<br>
<br>
