is there anyone who can give me some idea about how to program a
256*256 co-occurance matrix? mine takes quite a long time, and now it
is still working......probably it is wrong:(
thank you!

Yeah, it's probably smarter than me. :-)

Mightn't that be because it's actually spelt "co-occurrence"?
(occurrence - 2 "c"s, 2 "r"s, 2"e"s).

This is SO weird!! I'll have to send the damn word
as a byte array:
99 111 45 111 99 99 117 114 97 110 99 101
c o - o c c u r a n c e
Never had that happen before!
Cheers,
David

this is mine, one matrix total 4 matrix
;matrix_04::(i+1,j-1)<-->(i,j)
;point=0
;for i=0,x-1 do begin
; for j=0,x-1 do begin
; for k=0,x-2 do begin
; matrix_tmp_00=Oimage(*,k)
; matrix_tmp_01=Oimage(*,k+1)
; matrix_search=where(matrix_tmp_00 eq j)
; tag=n_elements(matrix_search)
; for l=0,tag-2 do begin
; if(matrix_search(l)-1 gt 0) then begin
; if((matrix_tmp_00(matrix_search(l)) eq
matrix_tmp_01(matrix_search(l)-1))) then begin
; point=point+1
; endif
; endif
; endfor
; endfor
; matrix_04(i,j)=point
; endf
