80 Million Tiny Images
June 29th, 2020 It has been brought to our attention [1] that the Tiny Images dataset contains some derogatory terms as categories and offensive images.

The dataset is too large (80 million images) and the images ar

Vehicle Detection, Tracking and Counting
There are several ways to perform vehicle detection, tracking and counting. An easy way to do vehicle detection is by using Haar Cascades (please, see Vehicle Detection with Haar Cascades section). Currently, I don't have a tutorial about it, but you can get some extra information in the OpenCV homepage, see Cascade Classifier page. Another way to do vehicle detection is by using Background Subtra
