here is my code i cannot understand the error in it can any one will help me to locate the error

close all;
clear;
%Read Background Image
Backg=imread('blk.jpg');
%Read Current Frame
CurrentFrame=imread('2.jpg');
%Display Background and Foreground
subplot(2,2,1);imshow(Backg);title('BackGround');
subplot(2,2,2);imshow(CurrentFrame);title('Current Frame');
%Convert RGB 2 HSV Color conversion
[Background_hsv]=round(rgb2hsv(Backg));
[CurrentFrame_hsv]=round(rgb2hsv(CurrentFrame));
Out = bitxor(Background_hsv,CurrentFrame_hsv);
%Convert RGB 2 GRAY
Out=rgb2gray(Out);
%Read Rows and Columns of the Image
[rows,columns]=size(Out);
BinaryImage = zeros(:, 'int8');
%Convert to Binary Image
for i=1:rows
  for j=1:columns
    if Out(i,j) >0
      BinaryImage(i,j)=1;
    else
      BinaryImage(i,j)=0;
    end
  end
end
%Apply Median filter to remove Noise
FilteredImage=medfilt2(BinaryImage,[5 5]);
%Boundary Label the Filtered Image
[L ,num]=bwlabel(FilteredImage);
STATS=regionprops(L,'all');
cc=[];
removed=0;
%Remove the noisy regions 
for i=1:num
  dd=STATS(i).Area;
  if (dd < 500)
    L(L==i)=0;
    removed = removed + 1;
    num=num-1;
  else
  end
end
[L2 ,num2]=bwlabel(L);
% Trace region boundaries in a binary image.

%Display results
subplot(2,2,3),  imshow(L2);title('BackGround Detected');

hold on;

Well, you could at least give a hint...since we don't have your input file, can't run it so not much can do simply by looking at the code without foreknowledge of what are supposed to be looking for...

I want to use this code for background removal and detection of breast masses

[Walter Roberson]

BinaryImage = zeros(:, 'int8');

is not valid syntax. You want

BinaryImage = zeros(rows, columns, 'int8');

By the way: what is the output of

logical(Out)

?

[bushra mughal]

Undefined function 'bakground' for input arguments of type 'char'.

[Walter Roberson]

You have no reference to anything like that in the code you posted. But if I were you I would change your code to refer to 'background' instead of 'bakground'
