09.12.2021 · 接着上篇DeepLab V2，本博文简单介绍下DeepLab V3（建议先去看下之前讲的DeepLab V1和DeepLab V2）。这是一篇2017年发表在CVPR上的文章。个人简单阅读完论文后感觉相比DeepLab V2有三点变化：1）引入了Multi-grid，2）改进了ASPP结构，3）把CRFs后处理给移除掉了。再吐槽一下，这篇论文看着感觉乱糟糟的。

The proposed `DeepLabv3' system significantly improves over our previous DeepLab versions without DenseCRF post-processing and attains ...

Atrous Convolution is introduced in DeepLab as a tool to adjust/control effective field-of-view of the convolution. It uses a parameter called ‘atrous/dilation rate’ that adjusts field-of-view. It is a simple yet powerful technique to make field of view of filters larger, without impacting computation or number of parameters.

DeepLabv3 : They augment the ASPP module with image-level feature to capture longer range information. They also include batch normalization ...

DeepLabv3 is a semantic segmentation architecture that improves upon DeepLabv2 with several modifications. To handle the problem of segmenting objects at multiple scales, modules are designed which employ atrous convolution in cascade or in parallel to capture multi-scale context by adopting multiple atrous rates.

Introduction

Deeplabv3-MobileNetV3-Large is constructed by a Deeplabv3 model using the MobileNetV3 large backbone. The pre-trained model has been trained on a subset of COCO train2017, on the 20 categories that are present in the Pascal VOC dataset. Their accuracies of the pre-trained models evaluated on COCO val2017 dataset are listed below. Resources

The DeepLab model addresses this challenge by using Atrous convolutions and Atrous Spatial Pyramid Pooling (ASPP) modules. This architecture has evolved over several generations: DeepLabV1 : Uses Atrous Convolution and Fully Connected Conditional Random Field (CRF) to control the resolution at which image features are computed.

17.06.2017 · In this work, we revisit atrous convolution, a powerful tool to explicitly adjust filter's field-of-view as well as control the resolution of feature responses computed by Deep Convolutional Neural Networks, in the application of semantic image segmentation. To handle the problem of segmenting objects at multiple scales, we design modules which employ atrous …
