Self.no nc + 5 # number of outputs per anchor

WebEach anchor box is tiled across the image. The number of network outputs equals the number of tiled anchor boxes. The network produces predictions for all outputs. Localization Errors and Refinement. The distance, or stride, between the tiled anchor boxes is a function of the amount of downsampling present in the CNN. Downsampling factors ...
