What is region proposal?
Region proposal: A candidate image region that might contain an object, generated before classification. Early detectors used hand-made methods such as selective search; later ones learned proposals with a network. Proposals narrow the search from every possible window to a manageable few thousand.
Region proposal: an example
Selective search may propose about 2,000 regions per image for R-CNN to classify.
