好记性不如烂笔头, 最近用Deeplab v2跑的图像分割,现记录如下。 官方源码地址如下:https://bitbucket.org/aquariusjay/deeplab-public-ver2/overview 但是此源码只是为deeplab网络做相应变形的caffe,如果需要fine tuning微调网络,还需要准备以下文件:
-
txt文件:文件中有数据集的名字列表的txt文件,训练测试集列表
-
训练好的init.caffemodel: 针对deeplab v2,作者有已经预训练好的两个模型参数:DeepLabv2_VGG16 和DeepLabv2_ResNet101
-
网络结构prototxt文件: train.prototxt和solver.prototxt,分别在:DeepLabv2_VGG16 和 DeepLabv2_ResNet101
-
官网脚本文件: 三个sh文件,建议使用脚本文件,初看虽不懂,但是比python版本的运行简单很多 注:本博客只涉及脚本版本的训练
cd ~
mkdir deeplab
cd deeplab
git clone https://bitbucket.org/aquariusjay/deeplab-public-ver2.git
mkdir -p ~/deeplab/exper/voc12/config/deeplab_largeFOV
mkdir -p ~/deeplab/exper/voc12/features/labels
mkdir -p ~/deeplab/exper/voc12/features2/labels
mkdir -p ~/deeplab/exper/voc12/list
mkdir -p ~/deeplab/exper/voc12/log
mkdir -p ~/deeplab/exper/voc12/model/deeplab_largeFOV
mkdir -p ~/deeplab/exper/voc12/res
有时候可能会打不开网页,无法访问,也可以在我的资源中下载,我已经原资料打包上传,无法在官网下载就点这里 如下:
以prototxt为后缀的网络结构文件train.prototxt 、test.prototxt 以及solver.prototxt文件移动到~/deeplab/exper/voc12/config/deeplab_largeFOV 文件夹下.
unzip prototxt_and_model.zip
mv *.prototxt ~/deeplab/exper/voc12/config/deeplab_largeFOV
mv *.caffemodel ~/deeplab/exper/voc12/model/deeplab_largeFOV
unzip link.zip
cd link
mv * ~/deeplab/exper/voc12
unzip list.zip
cd list
mv * ~/deeplab/exper/voc12/list
论文中提到的pascal voc训练,其使用的数据不只是官网下载的pascal-voc2012源数据,而是由voc2012和另外一个pascal voc2012增强数据集合并而成 。 具体数据整理步骤请看另一篇博客从头开始训练deeplab v2系列之二【VOC2012数据集】
对于其他图像分割的数据集,我们也可以处理成类似voc2012数据集的格式,进行fine tuning, 这里分别有对 pascal context数据集和nyu v2数据集的数据处理说明。
deeplab v2源码直接第一次使用的话确实有很多坑,其中除了数据集要注意的地方,大部分的坑在脚本文件。不过运行成功之后再换其他数据集,真的很方便,不需要改网络文件和文本文件,只需要修改脚本文件script,就会自动生成相应的网络结构文件和txt文件,所以学会修改脚本文件至关重要 训练速度相对于某些图像分割的网络超快,而且即使你的分类数超过255类,也没关系。 上图我选的459类的数据集训练结果
