[SOLVED] RE: "Magnetic lasso"-like tool

[Vera, Pedro L.]

I've been corresponding with Daniel Lelis Baggio, the developer of Live Wire about my inability to get it to work and he figured out the problem.

I had installed the ImageJ version that comes bundled with java and Livewire was trying to use that version of java rather than the other (newer; updated) version I had also installed in the system. Once I downloaded the No-Java imagej package, LiveWire works perfectly and it will be very useful for what I'm doing.

Thanks to all who responded with comments and suggestions.

Best regards,
Pedro

Hi,
Can someone please explain how to use the different settings of LiveWire:
"Exponential"
"Power"
"Magnitude"
"Direction"

I couldn't find any documentation.
Thank you.

I can't help about LiveWire, last time I tried it it was very slow.
I just would like to add my vote to the implementation of a simple
"magnetic lasso" tool, or even better a NeuronJ/Neurite Tracer tool
that could simply trace neurite-like objects in simple, 2D images. Yes
the emphasis in on "simple" here, having to use a full blown NeuronJ
(that runs "outside" of regular imageJ) or Neurite Tracer (that is a
huge overkill for that) really sucks... I dream about a simple tool
that would quickly trace neurites as a freeline selection. I
understand there are some heavy processing required (Laplacian and
such), but would it be possible to do the processing once when you
click on the tool and then have a responsive semi-automatic tracing
(similarly to what happens in NeuronJ) ?
I can't code it but I would be glad to help by any means to making it happen.

Versatile Wand yes but...
- for 1D (line selection), not 2D selections
- Computes the "ridgeness" of every path betwen the last validated
point and the current position of the cursor. I think the algorithm
behind NeuronJ and Neurite Tracer is much more precise and efficient
at detecting filament-like objetcs than the wand.
