本篇文章将详细讲解deform_conv2d的用法。 基本用法 1.引入相应的库和模块: importtorch importasnn importasF fromdeform_convimportDeformConv2d 2.定义一个简单的卷积神经网络模型: classConvNet(): def__init__(self): super(ConvNet,self).__init__() =(3,64, kernel_size=3, stride=1, padding=1...
接着,我们创建了输入张量,并使用DeformConv2d类构建了deform_conv2d层。最后,将输入张量传递给deform_conv2d层进行前向传播,并打印输出结果的大小。 在实际使用deform_conv2d时,可以参考以下几个方面的相关参考内容: 1.论文:deform_conv2d是根据CVPR2017论文《Deformable Convolutional Networks》中提出的。该论文详细...
其形状为batch_size, 2 * offset_groups * kh * kw, out_height, out_width。 由CycleMLP代码我们可以知道,deform_conv2d中的offset的含义是每次卷积划窗中,相对于每个采样点原始位置的相对偏移量,所以是有正有负,正表示轴向位置,负表示反向轴向位置。 这里为了分析offset_groups的效果,我们将其设置为3,即offs...
