This is a sample code for extrating dense flow field given a video.
Dependences:
- opencv3.1.0
只使用 i_dense_flow.cpp 即可
Usage:
git clone https://github.com/weimanzhou/dense_flow.git
cd dense_flow
g++ i_dense_flow.cpp -o i_dense_flow `pkg-config --cflags --libs opencv`
# 创建 source 文件夹，存放 avi 格式视频的位置
mkdir source
# 创建 target 文件夹，存放输出的默认位置
mkdir target
./i_dense_flow
# 执行后的 target 目录结构
# target
# |- avi_file_name
# |- image
# |- x_flow
# |- y_flow
# |- avi_file_name
# |- image
# |- x_flow
# |- y_flowExmaple:
