I want to change the dataset from 'cuhk03.mat' to 'cuhk03_detected_lomo.mat',when i run the same program,there has an erro shows
% >> prepare_imdb
Undefined variable "testsets" or class "testsets"
wrong in prepare_imdb (line 14)
test = testsets{testsets_num,1};
But there has no error when i use the 'cuhk03.mat'(the‘cuhk03_detected_lomo.mat' is a dataset which has been processed with LOMO characteristics).The complete code is as follows:
% clear;
%you can download this file. It contains data.
load('..\cuhk03-prepare-eval/cuhk03_detected_lomo.mat');
imdb.meta.sets = ['train','test'];
count = 0;
label = 0;
%choose a split
testsets_num = 6; %cuhk03 has 20 different splits, and this value can be 1 ~ 20.
p = sprintf('./split%d_256_1/',testsets_num);
if(~exist(p,'dir'))
mkdir(p);
end
test = testsets{testsets_num,1};
cc = [];
for k=1:numel(detected) %camera
im = detected{k,1};
for i = 1:size(im,1) %identity
A = find(test(:,1) == k);
B = find(test(:,2) == i);
C = intersect(A,B);
if(~isempty(C))
continue;
end
label = label+1;
temp = 0;
for j=1:10 %image
file = im{i,j};
url = sprintf('F:/2016_person_re-ID-master/2016_person_re-ID-master/cuhk03-prepare-eval/split%d_256/%d_%d_%d_1.jpg',testsets_num,k,i,j);
if(~isempty(file))
disp(url);
imwrite(imresize(file,[256,256]),url);
temp = temp + 1;
count = count + 1;
%disp(count);
imdb.images.data(count) = cellstr(url);
imdb.images.label(count) = label;
end
end
cc = [cc;temp];
end
end
imdb.images.set = ones(1,count);
imdb.images.set(:,randi(count,[round(0.1*count),1])) = 2;
list = find(imdb.images.set==2);
for i=1:numel(list)
if cc(imdb.images.label(list(i)))<9
imdb.images.set(list(i))=1;
end
end
save(sprintf('cuhk_data_256_split%d_1.mat',testsets_num),'imdb','-v7.3');

You are doing load() with no output arguments. That causes variables to be created in the current workspace. Your code then relies upon variables with those particular names existing. But what happens if what you load() has different variable names, or structures the information differently, or perhaps does not contain the information at all?

You didn’t define testsets
