Now, we have VGG-16, which contains 138,000,000 weights, and these millions of weights need to be executed each time the window moves a step, and we need to do this for different window sizes.
It's clear that this method is almost unusable, especially for real-time object detection.
The second drawback is that the algorithm is quite ...
