GStreamer plugins for IDS uEye cameras with frame analysis capabilities.
#### TODO
- [] idsueyesrc doesnt respect auto exposure set in ini file. need to be set in filter `exposure=0.5`
- []

### Basic capture from IDS uEye camera
```bash
gst-launch-1.0 idsueyesrc config-file=whole-presacler64_autoexp-binningx2.ini ! queue ! autovideosink
gst-launch-1.0 idsueyesrc config-file=ini/whole-presacler64_autoexp-binningx2.ini exposure=0.5 ! queue ! autovideosink
```
### Frame filtering based on column analysis
Drop frames when column mean deviates from rolling baseline by more than 0.5:
```bash
gst-launch-1.0 idsueyesrc config-file=whole-presacler64_autoexp-binningx2.ini ! videoconvert ! video/x-raw,format=GRAY8 ! rollingsum window-size=1000 column-index=1 threshold=0.5 ! queue ! autovideosink
gst-launch-1.0 idsueyesrc config-file=ini/whole-presacler64_autoexp-binningx2.ini exposure=0.5 ! videoconvert ! video/x-raw,format=GRAY8 ! rollingsum window-size=1000 column-index=1 threshold=0.5 ! queue ! autovideosink
```
**Note:** The `rollingsum` element analyzes a single column of pixels and drops frames when the column mean deviates from the rolling mean baseline by more than the threshold. Use `videoconvert` to ensure proper format negotiation.

Analyze column 320 with larger window:

```
Use stride for faster processing (sample every 2 rows):
```bash
gst-launch-1.0 idsueyesrc config-file=whole-presacler64_autoexp-binningx2.ini ! videoconvert ! video/x-raw,format=GRAY8 ! rollingsum window-size=1000 column-index=1 stride=2 threshold=0.5 ! queue ! autovideosink

```
Lower threshold for more sensitive detection:
```bash
gst-launch-1.0 idsueyesrc config-file=whole-presacler64_autoexp-binningx2.ini ! videoconvert ! video/x-raw,format=GRAY8 ! rollingsum threshold=0.2 ! queue ! autovideosink
