To run the application, you have to:
- The Tencent ncnn framework installed. Install ncnn
- OpenCV 32 bit installed. Install OpenCV 4.5
- Code::Blocks installed. (
$ sudo apt-get install codeblocks)
To run the application, you have to:
- A raspberry Pi 4 with a 32 or 64-bit operating system. It can be the Raspberry 64-bit OS, or Ubuntu 18.04 / 20.04. Install 64-bit OS
- 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/Face-detection-Raspberry-Pi-32-64-bits/archive/refs/heads/master.zip
$ unzip -j master.zip
Remove master.zip and README.md as they are no longer needed.
$ rm master.zip
$ rm README.md
Your MyDir/ncnn folder must now look like this:
Walk2.mp4 (demo video)
FaceDetection.cpb (code::blocks project file)
main.cpp (main example file)
ncnn_UltraFace.cpp (Ultra face class)
ncnn_UltraFace.hpp (Ultra face class)
RFB-320.bin (ncnn model)
RFB-320.param (ncnn topology file)
Slim_320.bin (ncnn model)
Slim_320.param (ncnn topology file)
The RFB-320 model recognizes slightly more faces than slim_320 at the expense of a little bit of speed. Choose the one you like.
