Try some examples from ESP-face, ESPino32Cam!
Hardware ESP32Cam from AI-Thinker/ArduCam-IOTai.
The detection performance are not bad with following results...
MTMN is a lightweight **Human Face Detection Model**, which is built around [a new mobile architecture called MobileNetV2](https://arxiv.org/abs/1801.04381) and [Multi-task Cascaded Convolutional Networks](https://arxiv.org/abs/1604.02878), and is specially designed for embedded devices.
Following diagram shows the workflow of MTNM.
