+# Virtual Background on stream effects
+
+> Inspired from https://ai.googleblog.com/2020/10/background-features-in-google-meet.html and https://github.com/Volcomix/virtual-background.git
+
+#### Canvas 2D + CPU
+
+This rendering pipeline is pretty much the same as for BodyPix. It relies on Canvas compositing properties to blend rendering layers according to the segmentation mask.
+
+Interactions with TFLite inference tool are executed on CPU to convert from UInt8 to Float32 for the model input and to apply softmax on the model output.
+
+The framerate is higher and the quality looks better than BodyPix
+
+#### SIMD and non-SIMD
+
+How to test on SIMD:
+1. Go to chrome://flags/
+2. Search for SIMD flag
+3. Enable WebAssembly SIMD support(Enables support for the WebAssembly SIMD proposal).
+4. Reopen Google Chrome
+
+More details:
+- [WebAssembly](https://webassembly.org/)
+- [WebAssembly SIMD](https://github.com/WebAssembly/simd)
+- [TFLite](https://blog.tensorflow.org/2020/07/accelerating-tensorflow-lite-xnnpack-integration.html)
