2013-05-13 22:32:25 -0500 asked a question how do I train SVM on images with different aspect ratios?

Can the SVM work on data with different dimensions? (using OpenCV's svm or libsvm) If the images have different size, I can resize to a standard value. But if they have different aspect ratios, it seems not to make sense to resize without keeping the original aspect ratio. Or shall I pad them with zeros to make them have the same aspect ratio?

This is a rather general question... how to reproduce algorithms from papers? When the code is not made available, it's hard to reproduce exactly. If available you are working on a different platform (e.g. windows vs linux, 32 vs 64 bit, c vs matlab vs python). Do you try to recode ?

I use dir(cv) or dir(cv2) after importing them. Anyone has a better solution since the documentation is incomplete?
