Region of Interest Pooling, or RoIPool, is an operation for extracting a small feature map (e.g., 7×7) from each RoI in detection and segmentation based tasks. Features are extracted from each candidate box, and thereafter in models like Fast R-CNN, are then classified and bounding box regression performed.

The actual scaling to, e.g., 7×7, occurs by dividing the region proposal into equally sized sections, finding the largest value in each section, and then copying these max values to the output buffer. In essence, RoIPool is max pooling on a discrete grid based on a box.

Papers per year the archive tags with this method, by the paper's archive date (620 dated). Bars are counts, not a trend claim.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
