Dependencies.

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 4.3
  
• 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/Yolact-ncnn/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:

girafe.jpeg
mumbai.jpg
onyx.jpeg
result_elephant.png
result_zebra.png
Yolact.cpb
yolact.cpp
yolact.bin (download this file from Gdrive )
yolact.param

---

Running the app.

Run Yolact.cpb with Code::Blocks.
For more info follow the instructions at Hands-On.

Yolact NCNN Android

Hi,
Do you have implemented an Demo Android app for Yolact with NCNN ? I would like to try out inference on it. It will be really helpful to me. Thank you in advance..
