Anchor size tuning in Faster R-CNN. I am training Faster R-CNN to detect small objects from UAV photography: 25x25 to 30x30 pixels. So far, I have done this with the default anchor dimensions given in the .config file: first_stage_anchor_generator { grid_anchor_generator { height_stride: 16 width_stride: 16 scales: 0.25 scales: 0.5 scales: 1.0 ... WebSep 16, 2024 · Anchors: For each sliding window, the network generates the maximum number of k- anchor boxes. By the default the value of k=9 (3 scales of (128*128, 256*256 and 512*512) and 3 aspect ratio of (1:1, 1:2 and 2:1)) for each of different sliding position in image. Therefore, for a convolution feature map of W * H, we get N = W* H* k anchor … port authority bus 355
