Question

我想上传1个文件夹中的所有图片，这些图片名称不同，但都是bmp。我想在之后处理它们。如何上传它们并用1个命令处理它们？

文件夹目录为C:\Users\Gramoz\Desktop\Gramoz\140917，下面显示了我必须逐个处理它们的代码（对于具有图像名称的特定文件夹）。

我只需要1个文件夹的mutiupload和multiprocess命令，因为代码可能不清楚。

fname = '103_Y(50)_Z(150)_EXP(8.159).bmp';
im = imread(fname);
figure(13)
imagesc(im)

C=max(max(im));
s=max(max(C));
[ROW COLUMN]=find(im==C);

row1 = ROW-17;
row2 = ROW+17;
col1 = COLUMN-17;
col2 = COLUMN+17;

Etot_min_BG = ( sum(sum(im))-(sum(sum(im(1:300,1:300)))/90000)*1024*1280);
Efoc = sum(sum(im(row1:row2,col1:col2)));
Efoc_min_BG = sum(sum(im(row1:row2,col1:col2))) - sum(sum(im(1:300,1:300)))/90000 * (row2-row1+1)*(col2-col1+1);

Nx = 1024; %Replace with real image dimensions 
Ny = 1280; %Replace with real image dimensions 
x0 = 451; %Replace with coordinate of MMF center
y0 = 644; %Replace with coordinate of MMF center
x = (1:Nx) - x0;
y = (1:Ny) - y0;
[X,Y] = meshgrid(x,y);
X = X';
Y = Y';

% im = (X.^2+Y.^2).*exp(-(X.^2+Y.^2)/50); %Comment out this line, 
temp = imread(fname); %Uncomment this line, write real file name
h = 1/81*ones(9);
im = filter2(h,temp);
% im = zeros(64,80);
% for k = 1:128
%     for m = 1:160
%         im(k,m) = sum(sum(temp((1+(k-1)*8):(k*8) , (1+(m-1)*8):(m*8))));
%     end
% end


[temp1 temp2] = cart2pol(X, Y);

r = reshape(temp2, Nx*Ny,1);

theta = reshape(temp1, Nx*Ny,1);

我只是根据 rayryeng 评论总结答案。因为代码的唯一区别应该是图像，就像上面说的那样，你只需要通过dir函数获取文件的名称，然后遍历不同的文件。

因此你应该有这样的东西：

images_names=dir(fullfile(images_path,'*.bmp'))
for i=1:length(images_names)
im = imread(fullfile(images_path,images_names(i).name));

%%% do your stuff here %%%%%%%%%%%%

%% if you need to save all in the same variable, and dont care how
save_F{i}=F; %%% like your F variable

%%%%%%%%%%%%%%%
end

从不同名称（所有bmp）的相同文件夹上载不同的图片并进行处理
