利用改进的脉冲神经网络完成灰度图像的分割

function Y = Jiabian(X)
[m,n] = size(X);
Y = zeros(m+2,n+2);

for i = 1:m+2
    for j = 1:n+2
        if i ==1&j~=1&j`=n+2
            Y(i,j)=X(1,j-1);
        elseif j == 1&i~=1&i~=m+2
            Y(i,j)=X(i-1,1);
        elseif i~=1&j==n+1&i~=m+2
            Y(i,j) = X(i -1,n);
        elseif i==m+2&j~=1&j~=n+2
            Y(i,j) = X(m,j-1);
        elseif i==1&j==1
            Y(i,j) = X(i,j);
        elseif i==1&j==n+2
            Y(i,j) = X(1,n);
        elseif i==m+2&j==n+2
