Re: How to measure a suite of photos taken from one sample?

Overlapping measurements seems like the way to go, it does not create the zero ring in the normalized values as opposed to no overlapping measurement. I am trying to work out a way to keep my fire years labels together with the whole radius so it pops out next time I open to compare it to other radii.

Re: How to measure a suite of photos taken from one sample?

The second option works well for me especially that I do have some sections scanned to higher resolution. There are also minor drawbacks. For example, the point labels are lost when creating a mean value curve. Also, when you match the 2 parts and no ring overlap (stop measuring at one ring and star...

BNDIff

When doing cross correlation and some other operations, you get a BNDiff value in the report. Is this the difference in correlation between the best and next best match?

Multi-radii cross correlation

I am building a chronology from living trees based on a big number of trees (>100 per species). I do have 4 radii from each of them. So when i do a cross correlation to see which are best match, radii from the same trees always match up even if the sum by stem button is checked. It would be lot of w...
