wasm face detection sample project for medium blog post

Face Detection on Web

This is the sample project for the medium post : Face Detection on Web Each sample directory is correspond to each blog post.

• sample1 : Build TFLite & OpenCV to WASM
• sample2 : WASM and SIMD with a Sample (Korean, English)

How to run

Common

• need emsdk version=2.0.15

> emcc -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.15
...

• Need node
• Cannot build with ARM Mac

Sample1

• Simple WebAssembly running test using node

> cd sample1
> mkdir cmake-build-wasm
> cd cmake-build-wasm

# build with SIMD instructions
> emcmake cmake .. -DTFLITE_WITH_WASM_SIMD=ON -DCMAKE_BUILD_TYPE=Release
# build without SIMD instructions
> emcmake cmake .. -DTFLITE_WITH_WASM_SIMD=OFF -DCMAKE_BUILD_TYPE=Release

> make -j 4
