Dear sir,
i have faced the following problem.Help me.Thanks all.
function pushbutton2_Callback(hObject, eventdata, handles)
if isfield(handles,'image')
% do stuff
Image=handles.image;
% Convert RGB image to gray scale image
%Main Program
I=Image;
k=1;p=1;
dim=ndims(I);
if dim==2
I=I;
else if dim==3
I=rgb2gray(I);
else fprintf('Nothing \n');
end
end
%imtool(I);
I=uint8(I);
I2=imopen(I,strel('disk',3));%before 3
%figure,imshow(I);
M=medfilt2(I2,[3 3]);
%imtool(M);
G=imgaussfilt(M,1);
%imtool(G);
%image=imsharpen(G);
AdjImg=imadjust(G);
%imtool(AdjImg);
initialT=mean2(AdjImg);
T=initialT;
Image=AdjImg;
[row,col]=size(Image);
newT=0;
while T-newT~=0
for i=1:row
for j=1:col
if Image(i,j)>=T;
Image(i,j)=Image(i,j);
else Image(i,j)=0;
end
end
j=j+1;
end
i=i+1;
%figure,imshow(Image);
m1=mean2(Image);
%m2=mean2(image);
newT=(m1)/2;

T=newT;
newT=formerT;
end
%figure,imshow(Image);
