MATLAB: How do i save extracted feature vectors of an image database

Question

Hello everybody

i have a DB of images for a CBIR project and i have to extract different types of features (color : using HSV, texture : using LBP) which i already did, now my qs is how to save those extracted features in a dataset of features to which the CBIR system would go back to, to retreive the similar images ? .. is it a ".mat" file or some other way ? and is it possible to gather the different types of features in the same dataset knoing that their vector sizes are different too? can anyone please help

Answer 1

Yes, you can save your variables in a .mat file. Use the save() function, like

save('answers.mat', 'var1', 'feature2', 'something3');

or whatever. They don't all need to be the same size or even class.
