Yolov8c2f结构是指在Yolov8模型的基础上添加了C2f结构。根据给出的引用,C2f是一个具有两个卷积层的CSP(Cross Stage Partial) Bottleneck模块。C2f的逻辑代码如下:
```python
class C2f(nn.Module):
def __init__(self, c1, c2, n=1, shortcut=False, g=1, e=0.5):
super().__init__()
self.c = int(c2 * e) # hidden channels
self.cv1 = Conv(c1, 2 * self.c, 1, 1)
self.cv2 = Conv((2 * n) * self.c, c2, 1)
self.m = nn.ModuleList(Bottleneck(self.c, self.c, shortcut, g, k=((3, 3), (3, 3)), e=1.0) for _ in range(n))
def forward(self, x):
y = list(self.cv1(x).chunk(2, 1))
y.extend(m(y[-1]) for m in self.m)
return self.cv2(torch.cat(y, 1))
```
在Yolov8c2f结构中,首先经过cv1层,然后使用`.chunk(2, 1)`将cv1层的输出结果按照第一维度分成两组,这里的2对应着`self.cv1 = Conv(c1, 2 * self.c, 1, 1)`中的2。接下来,对第一组的结果应用一系列的Bottleneck模块,然后将第二组的结果与Bottleneck模块的输出结果拼接在一起,最后通过cv2层进行输出。这就是Yolov8c2f结构的整体流程。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
