今天中午就要交的试卷，交不了，就悲剧了啊·
麻烦大大们帮帮忙啊！

% Input-output specs
输入输出 规则
% ------------------
% IM: N-D, real, full matrix
N-D实数全矩阵
% any numeric or logical nonsparse type
任何数字的 或者逻辑非系数 类型
% if islogical(IM), treated as binary
若是逻辑数则为真，以二进制对待。
% empty ok
空集 确定
% Infs ok
Infs确定
% if logical, NaNs are ok and treated as 0s, otherwise
如果合乎逻辑的，通知书是确定并视为0 ，否则
% not allowed.
％ ，不允许。
%
% CONN: connectivity
连接器 连通
%
% IM2: Same class and size as IM
IM2 ：同一等级，与IM相同的规模
[im,conn] = parse_inputs(varargin{:});
赋值
conn = conn2array(conn); 赋值
marker = im;
标记：im;
% Now figure out which elements of the marker image are connected to the

% outside, according to the connectivity definition.
现在，根据连接定义，指出标记图像的哪个单元 连接外部，
im2 = true(size(marker)); 赋值
im2 = padarray(im2, ones(1,ndims(im2)), 0, 'both'); 赋值
im2 = imerode(im2,conn); 赋值
idx = cell(1,ndims(im2)); 赋值
for k = 1:ndims(im2) 循环
idx{k} = 2:(size(im2,k) - 1);
end
im2 = im2(idx{:});

% Set all elements of the marker image that are not connected to the
% outside to the lowest possible value.
将标记图像 中所有 未连接到外部的 单元 设置为 可行的最小值

if islogical(marker) 如果为真
marker(im2) = false;
else
marker(im2) = -Inf;
end

im2 = imreconstruct(marker, im, conn);
if islogical(im2)
im2 = im & ~im2;
else
im2 = imsubtract(im,im2);
end

%%%
%%% parse_inputs
%%%
function [im,conn] = parse_inputs(varargin)

checknargin(1,2,nargin,mfilename);

im = varargin{1};
checkinput(im, {'numeric' 'logical'}, {'nonsparse' 'real'}, ...
mfilename, 'IM', 1);

if nargin < 2
conn = conndef(ndims(im),'maximal');
else
conn = varargin{2};
checkconn(conn,mfilename,'CONN',2);
end

% Skip NaN check here; it will be done by imreconstruct if input
这里跳过NaN检查 如果是双输入，则imreconstruct 函数可以解决。
% is double.
