           Options: m1,m2,m3,m4,m5,m6,m7

       te2=string[,string,...]
           Texture measures (required if te1 was specified):
                t1  =  contagion            t2  =  ang.  sec.  mom.      t3  =  inv.  diff.  mom. t4  =  entropy
           t5 = contrast
           Options: t1,t2,t3,t4,t5

       jux=string[,string,...]
           Juxtaposition measures (weight file in r.le.para needed):
                j1 = mn. juxtaposition              j2 = s.d. juxtaposition
           Options: j1,j2

       edg=string[,string,...]
           e1 = sum of edges  e2 = sum of edges by type (need edge file: r.le.para)

DESCRIPTION

       The  r.le.pixel  module contains a set of measures for attributes, diversity, texture, juxtaposition, and
       edge.
