checkchildren.m

EZW法是一個用matlab寫的程式,是植基於小波的影像壓縮轉換

function   RR=checkchildren(j,RR)
% if a symbol 't' is encounted, then make all its descendants in reference  
% matrix RR's components equal 1---ZEROTREES

global N
[m,n]=size(N);

for i=(4*j-3):4*j;
      if  i<=m, 
             
         RR(N(i,1),N(i,2))=1;
           
         RR=checkchildren(i,RR);
     
     end
    
       
end;
