Examples

Segments the tangram.pan image thanks to a k-means classification of the pixels based on mean and variance features:

   pmeanfiltering 1 tangram.pan moy.pan
   pvariancefilter 0 255 tangram.pan var.pan

   pim2array data.1 moy.pan data1.colc
   pim2array data.2 var.pan data2.colc
   parray2array data.1 Float data1.colc data1.cold
   parray2array data.2 Float data2.colc data2.cold
   pcolcatenateitem data1.cold data2.cold data3.cold
   parraysnorm data data3.cold data3.cold
