膨胀卷积,也叫空洞卷积,Dilated Convolution,也有叫 扩张卷积; 空洞卷积 是 2016在ICLR(International Conference on Learning Representation)上被提出的,本身用在图像分割领域,被deepmind拿来应用到语音(WaveNet)和NLP领域,它在物体检测也发挥了重要的作用,对于小物体的检测十分重要 普通卷积 先来看看 普通卷积 卷积后需...
如果一个目标物的长或宽长度小于16个pixel,训练label map需要下采样到与模型输出维度相同,即下采样16倍时已经丢失了许多细节, 对应的模型预测结果双线性插值上采样是无法恢复这个信息。 密集上采样卷积DUC (Dense Upsampling Convolution),做的事情就是改变原本top layer输出的shape,提高了小目标物的识别率,验证了DUC...
DeepLabv3+是在DeepLabv3上的改进，通过添加一个简单的解码器，在输出stride为4处添加2个3 × 3 conv...
So from this paper. “Multi-Scale Context Aggregation by Dilated Convolutions”, I was introduced to Dilated Convolution Operation. And to be honest it is just convolution operation with modified…

Secondly, the design of a dedicated dilated causal convolution block allows the model to have a receptive field as large as the input sequence length, while maintaining a reasonably low computational cost. Thirdly, by introducing a context stacking structure, the proposed model is capable of ...

Methods: We adopted similar hierarchal structures as the conventional U-Net and incorporated dilated kernels in each convolution to allow the network to observe larger, more robust features within the image without the requirement of downsampling and upsampling internal representations. Our dNet was ...
We proposed a parallel residual network based on dilated and depthwise separable convolutions. First, to increase the receptive field of the network and avoid the loss of features, dilated convolutions are used instead of the traditional convolution operation in the traditional residual blocks. Second...
