I am interested to use relevance feedback. I would like to use the MATLAB code of image retrieval with relevance feedback.
My problem is regarding the dataset, "corel100.mat". How can I get it?
I don't have the dataset - I tried, but I failed.
Can you please provide more information about what you need? Your "corel100.mat" dataset is in folder /Data/Retrieval and you can load it with load('Data/Retrieval/corel100.mat');
Check this link it might help.
Wish you luck for your Project

Hi Harun,
I need corel100.Mat to use i t in Image retrieval.
The corel100.Mat in the "Retrieval"folder, is wrong, i reconstruct this dataset bymyself.
When you run "Run_Retrieval_all, you find an error about "Label", because the reconstructed dataset is matrix composed of : the number of images * features.
Contrary when I read the instructions in README , the dataset is composed of :
(1) "Data": n*d data matrix; "n" is the number of images"d" is the dimension of images;
(2) "Labels": n*k label matrix, "k" is the number of categories.
-I don't undestand well if corel100 is matrix or cell? may be it is cell because it is composed of two matrices:Data and Labels.
-How to do it ? according to my understanding, i perform the following steps:
(A)save(''Data.mat','dat''),where the variable dat is matrix (images*dimensions)
(B)save(''Label.mat','lab''); where the variable lab is matrix (images*categories)
(C)save(''Corel100.mat','dat','l'ab')

Hi, Khadidja!
Now I finally understood everything.
That could work. Also, you can do it like this: make the matrices Label and Data in your workspace, delete everything else from the workspace and then save workspace as corel100.mat.
Your reasoning is correct, this mat file has to contain two matrices.
From that "readme" file, I have seen that the "corel100.mat" is copyrighted, and therefore not provided. I think it is may be a good idea that you contact the authors of the codes for more information. Here is the quoted notification from the author's readme.text file
"2.1. Download the retrieval data;
corel100.mat - COREL data (we are not able to provide the data due to copyright issue);"
