This repo implements the RoI Pooling, RoI Align & Precise RoI Pooling.
RoI Pooling & RoI Align are implemented by myself, only for study reference, while Precise RoI Pooling is original, proposed in the paper Acquisition of Localization Confidence for Accurate Object Detection, published at ECCV 2018 (Oral Presentation), about its usage, u can get a closer look at PreciseRoIPooling
