### Frame filtering based on column analysis ## WIP - Frame filtering based on column analysis

## Network Streaming
### Sending Line Scan Data Over UDP
#### Real Data Pipeline
Send camera data as raw UDP stream (note: 5ms exposure is too fast):
```powershell
gst-launch-1.0 idsueyesrc config-file=ini/200fps-2456x4pix-cw.ini exposure=5 framerate=300 `
! queue `
! udpsink host=127.0.0.1 port=5000
```
#### Python/OpenCV Receiver
Receive and process raw column data:
```pwsh
uv run scripts/recv_raw_column.py
```
Or with rolling analysis:
```pwsh
uv run .\scripts\recv_raw_rolling.py
```
See [`scripts/recv_raw_column.py`](scripts/recv_raw_column.py) for the Python implementation with debug options.
### Demo/Test Data Streaming
#### Sender (crop to first column, send raw over UDP)
```pwsh
gst-launch-1.0 -v `
videotestsrc pattern=smpte ! `
videocrop left=0 right=639 top=0 bottom=0 ! `
video/x-raw,format=RGB,width=1,height=640,framerate=30/1 ! `
udpsink host=127.0.0.1 port=5000
```
#### GStreamer Receiver (raw UDP → display)
```pwsh
gst-launch-1.0 -v `
udpsrc port=5000 caps="video/x-raw,format=RGB,width=1,height=640,framerate=30/1" ! `
videoconvert ! `
autovideosink
```
