Question

首先，选择一个输入图像，然后单击＆＃34;选择图像＆＃34;。

% Then you can
%   - add this image to database (click on "Add selected image to database"
% 
%  If you choose to add image to database, a positive integer (sign ID) is
%  required. This posivive integer is a progressive number which identifies
%  a person (each person corresponds to a class).
% For example:
%
%  - add "mike1.jpg" to database ---> the ID has to be 1 since Mike is the first
%    person you are adding to database
%  - add "mike2.jpg" to database ---> the ID has to be 1 since you have already
%    added a Mike's image to database
%  - add "paul1.jpg" to database ---> the ID has to be 2 since Paul is the second person
%    you are adding to database
%  - add "cindy1.jpg" to database ---> the ID has to be 3 since Cindy is
%    the third person you are adding to database
%  - add "paul2.jpg" to database ---> the ID has to be 2 once again since
%    you have already added Paul to database

如何分配此唯一标志ID ??

Answer 1

在加载图像并对其进行处理时，可以使用加载的确切名称进行保存。你也可以添加前缀和后缀。

有时，根据您的需要，您可以在图片名称末尾附加时间和日期。

在您的情况下，您在

中有filename

[filename, pathname, filterindex] = uigetfile('*.jpg', 'Pick a .jpg image');

做一些像：

[pathstr, name, ext] = fileparts(filename) 
newFileName = name + '_normalize' + ext;

您可以添加任何您想要的后缀

，而不是'_normalize'

如果您想添加日期和时间，可以使用datetime('now')
