Efficient Lane Detection Technique Based on Lightweight Attention Deep Neural Network

Figure 4

Structures of bottleneck layer unit with variant stride in group convolution. The first and the third convolutions in above structure are point convolution, while the second is group convolution. (a) Bottleneck with skip connection and stride of 1. The symbol “⊕” represents elementwise summation. (b) Bottleneck with stride of 2.
