[交流] 【求助】大家帮忙帮我看下用MATLAB仿真为什么直方图不出来

>> J=imread('RoadG1.jpg');
>> [x,y]=size(J);
>> I=double(J);
>> z0=max(max(I));
>> z1=min(min(I));
>> T=(z0+z1)/2;
>> TT=0;
>> s0=0;n0=0;
>> s1=0;n1=0;
>> allow=0.5;
>> d=abs(T-TT);
>> count=0;
>> while(d>=allow)
count=count+1;
for i=1:x
for j=1:y
   if  (I(i,j)>=T)
         s0=s0+I(i,j);
         n0=n0+1;
      end
      if  (I(i,j)          s1=s1+I(i,j);
         n1=n1+1;
      end
   end
end
T0=s0/n0;
T1=s1/n1;
TT=(T0+T1)/2;
d=abs(T-TT);
T=TT;
end
>> Seg=zeros(x,y);
>> for i=1:x
   for j=1:y
      if(I(i,j)>=T)
         Seg(i,j)=1;
      end
   end
end
>> J0=Seg;

底下总说错误
??? Error using ==> images\private\checkinput>check_attributes
Function IMHIST expected its first input argument, I or X,
to be two-dimensional.

Error in ==> images\private\checkinput at 37
check_attributes(A, attributes, function_name, variable_name, ...

Error in ==> imhist>parse_inputs at 198
checkinput(a, {'double','uint8','logical','uint16'}, {'2d'}, mfilename, ['I or ' ...

Error in ==> imhist at 49
[a, n, isScaled, top, map] = parse_inputs(varargin{:});
这个应该怎么改呢？
