Dear All,
I am using k-means Clustering to measure the blue and red in my
images. I use the threshold to move from one cluster to another. In
some images the k-means clustering could produce very good matches
(I'd say spot on), but in others the results were less desirable. My
settings are
Number of clusters to: 4
Cluster center tolerance: 0.0001
Enable randomization seed: ticked
Randomization seed: 48
The other options were not ticked
Could I do anything more to improve the analysis? and... Is it
possible to pre-define the red and blue clusters (ie, assign cluster
1 to be blue)?
Any help will be appreciated. Thanking you.
