SNIP

SNIP, or Scale Normalization for Image Pyramids, is a technique used for object detection in computer vision. It is a multi-scale training scheme that selectively back-propagates the gradients of object instances of different sizes as a function of the image scale. What is multi-scale training? Multi-scale training (MST) is a technique used for object detection in computer vision that involves observing each image at different resolutions. This is because at a high resolution, large objects a
