hi, in r2014a,I build a 3d modeling from 2d array when i build it with this code, the detection of part of shape in fill function matlab

 has wrong
 zada = imfill(phi,'holes');

if(k==35)||(k==7)||(k==1)||(k==2) originalImage = bwareaopen(im2bw(zada),110); elseif (k==2)||(k==1) originalImage=bwareaopen(im2bw(zada),30); else originalImage = bwareaopen(im2bw(zada),30); end imshow(originalImage); % se = strel('disk',10);

if(k==8)||(k==9)||(k==10)||(k==6)||(k==7)||(k==5) se = strel('disk',10); else se = strel('line',4,95); %# structuring element end closeBW = imclose(originalImage,se);

closeBW=imfill(mat2gray(closeBW),'holes'); figure(222222222) imshow(closeBW); numberOfPixels1 = sum(closeBW(:)) numberOfPixels2 = bwarea(closeBW) structBoundaries = bwboundaries(closeBW); xy=structBoundaries{1}; % Get n by 2 array of x,y coordinates.

blackMaskedImage = asl1;
blackMaskedImage(~closeBW) = 0;
curve3_smooth=mat2gray(blackMaskedImage);
figure(23333)
imshow(curve3_smooth)
%  fact(:,:,k)=blackMaskedImage;
%%%%%%%%%%%%%%
% closeBW=curve3_smooth;
fact(:,:,k)=mat2gray(closeBW);
 figure(3333331)
 imshow(fact(:,:,k));
       end
D=fact;
D=imfill(mat2gray(D),'holes');
D = squeeze(double(D));
D = smooth3(D);
D(isnan(D)) = 0;
%  
%  [x,y,z,D] = subvolume(D,[nan,nan,nan,nan,nan,nan]);
D=imfill(D,'holes');
thresh = max(D(:)) /2;
FV = isosurface(D,thresh);
%  FV = isosurface(D,5);
  reduce=0.25;
  if (reduce ~= 1.0) %next: simplify mesh
      FV = reducepatch(FV,reduce);
  end;
ec = 'none';
p1 = patch(FV,...
