HI! I download dataset from gdo152.ucllnl.org (15 cm per pixel) and right now have: 6 700 positive tiles (with vehicle) and 7 000 negative (other object&nature) each 120x120 pixel. Then I training HOG + linear SVM, test on learning data with this result: True Positives: 6409 True Negatives: 6393 False Positives: 607 False Negatives: 309 and when I test my descriptor on Selwyn aerial, I have a lot of false positive and negative alarm (red circle) C:\fakepath\8.png C:\fakepath\9.png how to make result better: -it is possible to make samples less? -apply filters? -Change the ratio of positive and negative images in the training sample?
I will be happy with the advice. Thank you! C:\fakepath\15.png
