Cascade Corner Pooling
Cascade Corner Pooling
**Cascade Corner Pooling** is a pooling layer for object detection that builds upon the [corner pooling](https://paperswithcode.com/method/corner-pooling) operation. Corners are often outside the objects, which lacks local appearance features. [CornerNet](https://paperswithcode.com/method/cornernet) uses corner pooling to address this issue, where we find the maximum values on the boundary directions so as to determine corners. However, it makes corners sensitive to the edges. To address this problem, we need to let corners see the visual patterns of objects. Cascade corner pooling first looks along a boundary to find a boundary maximum value, then looks inside along the location of the boundary maximum value to find an internal maximum value, and finally, add the two maximum values together. By doing this, the corners obtain both the the boundary information and the visual patterns of objects.
