我正在测试来自不同卷积层的SSD输出,而不是原始的'conv4_3', 'fc7', 'conv6_2', 'conv7_2', 'conv8_2', 'conv9_2'
。
我的想法是,如果图层的接收场与对象的边界框匹配,它将具有更好的检测率。
因此,我仅从具有与我的训练对象大小相似的接受域大小的图层中获取输出。
因此,我从'conv3_3', 'conv4_1', 'conv4_2', 'conv4_3'
获取输出。那我就不用
也def AddExtraLayers(net, use_batchnorm=True, lr_mult=1):
。
问题是当我测试时,我没有任何检测。
我看到的是,detection_eval比使用那些原始输出层低。几行训练输出如下所示。我的实施方式可能有什么问题?
