1 、Li探索了一个新的更深层的Atrous Spatial Pyramid Pooling module (ASPP),并应用了长短残差连接以及深度可分离卷积,从而得到了一个更快、更有效的分割模型。LiteSeg体系结构在多个backbone上进行测试,如Darknet19、MobileNet和ShuffleNet,在准确性和计算成本之间提供多重权衡。以MobileNetV2为主干网的LiteSeg模型,在Cityscapes数据集上针对640×360分辨率的图像以每秒161帧的速度,达到了67.81%的mIoU精度。 2 、基于编解码结构、Atours Spatial Pyramid Pooling (ASPP)、空洞卷积和深度可分离卷积,论文设计了一种能够适应任何backbone的LiteSeg结构。通过选择不同的backbone,将允许在计算成本和精度之间进行权衡,以满足多种需求。 主要有两点: 2.1、提出了一种实时有竞争力的网络结构,并用三种不同的backbone Darknet19、MobileNetV2和ShuffleNet进行了测试,在Cityscapes数据集上实现
