For exemple in one gray image (defined by "j"). The minimun value is 0
 ("vj_min" = 0.0)and the maximun value is 255 ("vj_max" = 255.0), but the 
construction of the histogram can not start and finish in the first and last
 bin. In others words "j_min" is the start bin and "j_max" is the last bin use
 for image representation (or histogram construction). 

the start and last values use for histogram construction is defined by 
start    (vj_max - vj_min)*j_min/nbin_j
last     (vj_max - vj_min)*j_max/nbin_j

"total" === Histogram data number

histogram dimensions are defined by  "DimenI" and "DimenJ" 
  the bin position (i,j) is obtained by  j*DimenI+i
