Question

我在2016年的matlab工作。我有一个程序代码。它需要正常工作。这是程序：

    clear all;    
addpath('..');    
training_files = dir('cootes/*.bmp.mat');    
for i=1:numel(training_files)
    load(sprintf('cootes/%s', training_files(i).name));     
    app = imread(sprintf('cootes/%s', training_files(i).name(1:end-4)));

    % Map RGB colors to [0,1]
    appearances(:,:,:,i) = double(app) ./ 255;      
    shapes(:,:,i) = xy2ij(annotations, size(app,1));
end     
load('cootes/triangulation.mat');    
test_img = 2;
one_out = [1:test_img-1, test_img+1:size(shapes,3)];    
AAM = build_model_2d(shapes(:,:,one_out), appearances(:,:,:,one_out), 'triangulation', triangulation);    
fprintf('\n******************************************************* 2D FITTING *******************************************************\n\n');
disp 'Figure 1: leave-one-out fitting result (red mesh) using as intialization a random shape from the training set (blue mesh).'
disp 'Figure 2: reconstructed appearance.'
disp 'Usage: Hit a random key to use a different initialization shape. Use CTRL+C to quit.'
fprintf('\n');    
while 1
    init_shape = one_out(round(rand()*(numel(one_out) - 1) + 1));
    try
        [ fitted_shape fitted_app ] = fit_2d(AAM, shapes(:,:,init_shape) + repmat([-5 -5], [size(shapes, 1) 1 1]), appearances(:,:,:,test_img), 20);

        figure(1)
        imshow(appearances(:,:,:,test_img));
        hold on;
        triplot(AAM.shape_mesh, shapes(:,2,init_shape), shapes(:,1,init_shape), 'b');
        triplot(AAM.shape_mesh, fitted_shape(:,2), fitted_shape(:,1), 'r');
        hold off;           
        figure(2)
        imshow(fitted_app);             
        pause;
    catch ME
        fprintf('Fitting diverged: %s\n', ME.message);
    end
end

启动程序后出现以下错误：

Undefined function or variable 'shapes'.

Error in annotate_test (line 29)
AAM = build_model_2d(shapes, appearances, 'triangulation', triangulation);

任何人解释为什么没有定义变量'shapes'。虽然清楚地说明了：

shapes(:,:,i) = xy2ij(annotations, size(app,1));

请帮助，我是新手，不明白哪里可能是错误。

Answer 1

training_files = dir('cootes/*.bmp.mat'); %error is here

试试这个。

training_files = dir(fullfile(mypath,'*.bmp.mat')); % should work if you have .bmp.mat files in that path

为什么我得到错误：未定义的函数或变量'形状'
