#1281: i.cluster not working with a high sample count
----------------------------+-----------------------------------------------
Reporter: nedhorning | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: Default | Version: unspecified
Keywords: cluster sample | Platform: Linux
Cpu: x86-64 |
----------------------------+-----------------------------------------------
I am using i.cluster on GRASS 7.0 on a 64-bit Ubuntu computer.
If I use the default values for "sample" and "min_size" i.cluster works
but if I set "sample=5,5" the resulting signature file only has one class.
When I enter "sample=5,5" I assume that every fifth pixel from every fifth
line is being sampled for use in calculating the cluster statistics. This
is apparently too many samples for i.cluster to handle. If I use
"sample=100,100" the program appears to work. I have a feeling that the
sample array is not able to handle a large number of samples but have not
verified this. It would be nice to be able to use "sample=1,1" even on
large images.
