Datasets to train SVM classification

I tried to train my own SVM to detect people from video.

Here is how I did it: https://stackoverflow.com/questions/5...

I think the problem is with my dataset. I used INRIA dataset.

Here is how it looks like: https://drive.google.com/drive/folder...

There are about 200 positive samples and about 1400 negative.

I want ask you if you know any other datasets which I can download and use with my SVM?

Do you have also any advice on how a well-prepared database should look like?

I want train my SVM to detect the silhouette of a specific person from video. But for now every dataset will be fine becasue I want just check if my code works. P.S. When I put data from INRIA it looks like my SVM doesn't learn anything.

could you expand "specific person"

what is your OpenCV version?

My OpenCV version is 3.4.1. Specific person = detect only one particular person like only detecting iron man from video :). But for now, dataset to detect all people from video will be just fine :)

Yes I have. I changed the format of all photos to png and their size on 64x128.

do you still have original pictures

resizing to 64x128 makes them useless
