WebFormally, we assign an RoI of width w and height h (on the input image to the network) to the level Pk of our feature pyramid by: k = [k0 + log2(√wh/224)]. Analogous to the ResNet based Faster RCNN system, we set k0 to 4. We attach predictor heads (in Fast R-CNN the heads are class-specific classifiers and bounding box regressors) to all RoIs ... WebMay 22, 2024 · Hence, the network can now detect effectively small scale object too. Source. To conclude, Feature Pyramid Network (FPN) is a deep convolutional neural network which makes use of “Feature Pyramids” made of feature maps instead of images, at multiple scales to make prediction.
