figure
subplot(221)
imshow(d);
picture_1 =d;% imread(strcat(save_path,picture_name));          %建立循环函数依次读取原始图像
picture_1 =imread('1.bmp');
    imshow(picture_1);
    [x,y]=ginput(2);
    picture_2 = imcrop(picture_1,[x(1),y(1),abs(x(1)-x(2)),abs(y(1)-y(2))]);
    figure
    imshow(picture_2)
    figure
    a1=picture_2(:,:,1);
