# Mac Track — Computer Vision Lab
Local object detection for Apple Silicon (M1/M2/M3) Macs using MediaPipe and YOLOv8 via OpenCV.
## Setup
Open a terminal, navigate to your project folder, and run:
```bash
python3 -m venv venv
source venv/bin/activate
pip install --upgrade pip
pip install opencv-python mediapipe ultralytics
```
Then download the MediaPipe EfficientDet model:
```bash
curl -L -o efficientdet.tflite "https://storage.googleapis.com/mediapipe-models/object_detector/efficientdet_lite0/int8/1/efficientdet_lite0.tflite"
```
## Scripts
| Script | Description |
|---|---|
| `yolo.py` | YOLOv8 object detection on your webcam, GPU-accelerated on Apple Silicon. Supports photo and video capture. |
| `yololive.py` | Live webcam feed with ghostly/glitchy pose and object detection overlays. |
| `yolopost.py` | Batch processes all videos in `input/`, adds object and pose overlays, and saves results to `output/`. |
| `pose.py` | Real-time human pose (skeleton) tracking via MediaPipe. |
| `poseobj.py` | Real-time multi-object tracking via MediaPipe. |
| `emojihead.py` | Overlays an emoji on up to four detected faces in your webcam feed. |
## Examples - Running
**MediaPipe** — lightweight CPU pipeline using Google's Tasks API:
```bash
python poseobj.py
or
python emojihead.py
```
**YOLOv8** — high-accuracy detection accelerated on Apple Silicon GPU via Metal Performance Shaders:
```bash
python yolo.py
or
python yololive.py
```
## Keyboard Controls
| Key | Action |
|---|---|
| `SPACE` | Capture a PNG snapshot with tracking boxes |
| `r` | Start / stop video recording |
| `q` | Quit and close all windows |
