Does any one know how to use lookup command under envi programming?
for an example I have used it like this ...
class_names = ['Unclassified', 'Glass', 'Cell Walls', 'Nuclei',
'Cytoplasm', 'Stroma Blood Vessel']
lookup = [[0,0,0], [255,255,255],
[0,0,255],[255,0,0],[0,255,0],[0,125,125]]
;run the classification
envi_check_save, /classification
class_doit, fid=fid, pos=pos, dims=dims, out_name=kmeans_out_name, $
method=7, r_fid=c_fid, mean=mean, $
out_bname="Kohonen Classifier", iterations=1, change_thresh=0.1, $
num_classes=num_classes, lookup=lookup,stdv=stdv, in_memory=0, $
class_names=class_names, Thresh = ((total(mean)) / nbands) * 1.968
however when I run the program ... classes are colored differently..
Does anyone know how to use lookup properly ..
thank you
