如何使用Matlab可视化LabelMe数据库

Question

可以从http://www.cs.toronto.edu/~norouzi/research/mlh/data/LabelMe_gist.mat

下载LabelMe数据库

但是，还有另一个链接http://labelme.csail.mit.edu/Release3.0/ 该网页有一个工具箱，但我找不到任何要下载的数据库。所以，我想知道我是否可以使用具有以下字段的LabelMe_gist.mat。字段names包含图像的标签，img可能包含图像。如何显示培训和测试图像？我试过了

  

    

im = imread（img）     使用imread＆gt; parse_inputs时出错（第486行）     filename或url参数必须是字符串。

  

imread错误（第336行） [filename，fmt_s，extraArgs，msg] = parse_inputs（varargin {：}）;

但肯定不是这样的。请帮忙

load LabelMe_gist.mat;
load('LabelMe_gist.mat', 'img')

Answer 1

由于我们从您的帖子中不知道这是什么类型的数据，所以我继续下载并下载它。事实证明，img是22019张大小为32x32（RGB）的图像的集合。这就是32 x 32 x 3 x 22019是i变量的原因。因此，imshow(img(:,:,:,i));图像可通过for iImage = 1:size(img,4) figure(1);clf; imshow(img(:,:,:,iImage)); drawnow; end
