To run the application, you have to:
- The Tencent ncnn framework installed. Install ncnn
- OpenCV 64 bit installed. Install OpenCV 4.5
- Code::Blocks installed. (
$ sudo apt-get install codeblocks)
To extract and run the network in Code::Blocks
$ mkdir MyDir
$ cd MyDir
$ wget https://github.com/Qengineering/LFFD-ncnn-Raspberry-Pi-4/archive/refs/heads/main.zip
$ unzip -j master.zip
Remove master.zip, LICENSE and README.md as they are no longer needed.
$ rm master.zip
$ rm LICENSE
$ rm README.md
Your MyDir folder must now look like this:
images folder
Walks2.mp4
FaceDetection_LFFD_ncnn.cpb
main.cpp
LFFD_ncnn.h
LFFD_ncnn.cpp
train_10_320_20L_5scales_v2_iter_1000000.bin
train_10_560_25L_8scales_v1_iter_1400000.bin
symbol_10_320_20L_5scales_v2_deploy.param
symbol_10_560_25L_8scales_v1_deploy.param
To run the application load the project file FaceDetection_LFFD_ncnn.cbp in Code::Blocks.
Next, follow the instructions at Hands-On.
