设计MATLAB图形界面，包括参考影像、带配准影像文件读取，控制点存储，配准后的影像写入等功能。给出代码

好的，我可以为您提供一个MATLAB图形界面的示例代码，包括参考影像、带配准影像文件读取，控制点存储，配准后的影像写入等功能。请注意，代码仅供参考，您需要根据自己的实际情况进行修改和调整。

% 创建GUI
f = uifigure('Name', '图像配准');
f.Position = [200 200 800 600];

% 设计布局
hAxes1 = uiaxes(f);
hAxes1.Position = [50 300 300 250];
hAxes2 = uiaxes(f);
hAxes2.Position = [400 300 300 250];
hText1 = uilabel(f);
hText1.Text = '参考影像:';
hText1.Position = [50 570 100 20];
hText2 = uilabel(f);
hText2.Text = '带配准影像:';
hText2.Position = [400 570 100 20];
hButton1 = uibutton(f, 'push', 'Text', '读取文件', 'Position', [50 530 100 30]);
hButton2 = uibutton(f, 'push', 'Text', '读取文件', 'Position', [400 530 100 30]);
hText3 = uilabel(f);
hText3.Text = '控制点:';
hText3.Position = [50 470 100 20];
hEdit1 = uieditfield(f, 'Text', '', 'Position', [50 430 300 30]);
hButton3 = uibutton(f, 'push', 'Text', '保存', 'Position', [400 430 100 30]);

% 添加回调函数
hButton1.ButtonPushedFcn = @readRefImage;
hButton2.ButtonPushedFcn = @readRegImage;
hButton3.ButtonPushedFcn = @saveRegImage;

% 全局变量
refImage = [];
regImage = [];
ctrlPts = [];

% 回调函数1：读取参考影像
function readRefImage(src, event)
    global refImage
    [file, path] = uigetfile({'*.jpg;*.tif;*.png;*.gif', '图像文件'}, '选择参考影像');
    if isequal(file,0) || isequal(path,0)
        return;
    end
    refImage = imread(fullfile(path, file));
    imshow(refImage, 'Parent', hAxes1);
end

% 回调函数2：读取带配准影像
function readRegImage(src, event)
    global regImage
    [file, path] = uigetfile({'*.jpg;*.tif;*.png;*.gif', '图像文件'}, '选择带配准影像');
    if isequal(file,0) || isequal(path,0)
        return;
    end
    regImage = imread(fullfile(path, file));
    imshow(regImage, 'Parent', hAxes2);
end

% 回调函数3：保存配准后的影像
function saveRegImage(src, event)
    global regImage ctrlPts
    if isempty(regImage) || isempty(ctrlPts)
        return;
    end
    [file, path] = uiputfile({'*.jpg;*.tif;*.png;*.gif', '图像文件'}, '保存配准后的影像');
    if isequal(file,0) || isequal(path,0)
        return;
    end
    tform = fitgeotrans(ctrlPts(:,1:2), ctrlPts(:,3:4), 'projective');
    regImageRegistered = imwarp(regImage, tform);
    imwrite(regImageRegistered, fullfile(path, file));
end

% 回调函数4：选择控制点
hAxes1.ButtonDownFcn = @selectCtrlPts;
hAxes2.ButtonDownFcn = @selectCtrlPts;
function selectCtrlPts(hObject, event)
    global refImage regImage ctrlPts
    if isempty(refImage) || isempty(regImage)
        return;
    end
    [x, y] = ginput(1);
    if hObject == hAxes1
        imshow(refImage, 'Parent', hAxes1);
        hold(hAxes1, 'on');
        plot(hAxes1, x, y, 'r+', 'MarkerSize', 10);
        hold(hAxes1, 'off');
        [x2, y2] = ginput(1);
        imshow(regImage, 'Parent', hAxes2);
        hold(hAxes2, 'on');
        plot(hAxes2, x2, y2, 'r+', 'MarkerSize', 10);
        hold(hAxes2, 'off');
        ctrlPts = [ctrlPts; x y x2 y2];
        hEdit1.Value = mat2str(ctrlPts);
    end
end

end
