Fast corner detection on a $2 ESP32-S3 with SIMD
What is SIMD-accelerated computer vision on a $2 microcontroller?
The author rewrote the FAST feature detector in assembly to use the ESP32-S3’s 128-bit SIMD instructions. It processes a 320×240 image in about 6 ms, roughly twice as fast as the reference implementation.
Who it is for
Embedded developers and hobbyists can now add real-time vision to cheap Wi-Fi boards without needing a GPU.
