Corner Pooling
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
Corner Pooling is a pooling technique for object detection that seeks to better localize corners by encoding explicit prior knowledge. Suppose we want to determine if a pixel at location (i, j) is a top-left corner. Let fₜ and fₗ be the feature maps that are the inputs to the top-left corner pooling layer, and let f_(tᵢⱼ) and f_(lᵢⱼ) be the vectors at location (i, j) in fₜ and fₗ respectively. With H ×W feature maps, the corner pooling layer first max-pools all feature vectors between (i, j) and (i, H) in fₜ to a feature vector tᵢⱼ , and max-pools all feature vectors between (i, j) and (W, j) in fₗ to a feature vector lᵢⱼ. Finally, it adds tᵢⱼ and lᵢⱼ together.

Tasks archive 2025-07-28
19 tasks the archive attaches to papers tagged with this method, by distinct papers. A task without a page in the catalog is plain text.
Usage over time archive 2025-07-28
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).
