The output of YOLOv2 has shape (13, 13, B* (5+C)), where B is the number of anchor boxes and C is the number of classes you're trying to detect. Thus the output has 13*13=169 grid cells. You can think of them as a division of the input image into 13 by 13 cells. rowenta grill + back center

Feature 0 is the objectness score, features 1–2 are the x and y scales of the box, features 3–4 are the x and y offsets of the box center (relative to the cell coordinate itself), and features 5–24 are the 20 class scores. All this — for the first anchor.

Webing anchor boxes can signiﬁcantly improve the accuracy (≥ 1%mAPabsolutegainwithYOLOv2)overthebaseline method. Meanwhile, the robustness is also veriﬁed towards different anchor box initializations and the improvement is consistent across different number of anchor shapes, which greatly simpliﬁes the problem of …

WebEach anchor box represents a specific prediction of a class. For example, there are two anchor boxes to make two predictions per location in the image below. Each 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. WebThe process is replicated for every network output. The result produces a set of tiled anchor boxes across the entire image. Each anchor box represents a specific prediction …
