mri brain tumor segmentation matlab code

[shabeer]

Code:

function code=Dec2Binfar(Tcod8,DIFLcd)
LT=length(Tcod8);
Lcd=LT*8-DIFLcd;
k=8;
for j=1:LT
   for i=0:7
       cd(k-i)=fix(Tcod8(j)/(2^(7-i)));
       if Tcod8(j)>=2^(7-i)
           Tcod8(j)=Tcod8(j)-2^(7-i);
       end;
   end;
       k=k+8;
end;
for i=1:Lcd
   code(i)=cd(i);
end;

Code:

function [DIFLcd,Tcod8]=Binfar2Dec(code)
L=length(code);
Lcd=round(L/8);
if mod(L,8)<4
  if mod(L,8)~=0
     Lcd=Lcd+1;
  end
end
Lcdn=(Lcd)*8 ;
DIFLcd=(Lcdn)-L ;
codn=zeros(1,Lcdn);
k=1;
for i=1:L
   codn(k)=code(i);
   k=k+1;
end
Tcod8=zeros(1,Lcd);
k=1;
for i=1:Lcd
  for j=0:7
 Tcod8(i)=(codn(k+j))*(2^j)+Tcod8(i);
   end;
 k=k+8;
end;

Code:

%If you have your vector of pulses for example:
%code=[1 0 0 0 1 0 1 1 0 1 0 1 0 0 0 1 0 1 1 1 1];%This is the which we want to cmpress it.
%Now we can call to our function :
%[DIFLcd,Tcod8]=Binfar2Dec(code)
%DIFLcd =
%    5
%Tcod8=
%    139 81 120
%Here code is the Input, DIFLcd and Tcod8 are the Output, in DIFLcd=5 is
%the value of zeros added to the end of the code vector to be able to
%translate it to decimal values: DIFLcd=length(Tcod8)*8-length(code)
%We can use this function only with values of vetors 0 or 1.
