SYNOPSIS

       r.le.pixel
       r.le.pixel help
       r.le.pixel  [-euz]  map=string   [sam=string]    [reg=string]    [att=string[,string,...]]
       [div=string[,string,...]]              [te1=string]              [te2=string[,string,...]]
       [jux=string[,string,...]]   [edg=string[,string,...]]   [--verbose]  [--quiet]

   Flags:
       -e
           Output map 'edge' of edges given a '1' in r.le.para/edge file

       -u
           Output maps 'units_x' with sampling units for each scale x

       -z
           Output map 'zscores' with standardized scores

       --verbose
           Verbose module output

           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.
