TensorFlow_Lite_Segmentation_RPi_64-bit

TensorFlow Lite Segmentation running on bare Raspberry Pi 4 with 64-bit OS

A fast C++ implementation of TensorFlow Lite Unet on a bare Raspberry Pi 4. Once overclocked to 1850 MHz, the app runs at 7.2 FPS! Special made for a bare Raspberry Pi 4 see Q-engineering deep learning examples

Benchmark.

Frame rate Unet Lite : 4.0 FPS (RPi 4 @ 1900 MHz - 32 bits OS)
Frame rate Unet Lite : 7.2 FPS (RPi 4 @ 1875 MHz - 64 bits OS)

Dependencies.

To run the application, you have to:

• A raspberry Pi 4 with a 64-bit operating system. It can be the Raspberry 64-bit OS, or Ubuntu 18.04 / 20.04. Install 64-bit OS
  
• TensorFlow Lite framework installed. Install TensorFlow Lite
  
• OpenCV 64 bit installed. Install OpenCV 4.5
  
• Code::Blocks installed. ($ sudo apt-get install codeblocks)

---

Installing the app.

To extract and run the network in Code::Blocks
$ mkdir MyDir
$ cd MyDir
$ wget https://github.com/Qengineering/TensorFlow_Lite_Segmentation_RPi_64-bit/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 folder must now look like this:
cat.jpg.mp4
deeplabv3_257_mv_gpu.tflite
TestUnet.cpb
Unet.cpp

---

Running the app.

Run TestUnet.cpb withCode::Blocks. More info or
if you want to connect a camera to the app, follow the instructions at Hands-On.
I fact you can run this example on any aarch64 Linux system.
