a是普通的卷积过程(dilation rate = 1),卷积后的感受野为3 b是dilation rate = 2的空洞卷积,卷积后的感受野为5 c是dilation rate = 3的空洞卷积,卷积后的感受野为8
dense prediction problems such as semantic segmentation ... to increase the performance of dense prediction architectures by aggregating multi-scale contextual information(来自[1])
当前层的感受野计算公式如下,其中, 表示当前层的感受野, 表示上一层的感受野, 表示卷积核的大小
四、潜在的问题及解决方法
