Web25 feb. 2024 · The IoU here is an evaluation index characterizing the accuracy of the marked reflective area. It is the overlap rate of the marked reflective area (Ø) and the subjectively evaluated reflective area (φ). It is also the ratio of their intersection to the union. The ideal case is full overlap: IoU = 1. Its calculation formula is shown in (17). WebNow we got a onnx model with Q&DQ layers.
