|
||||
## Usage Examples
|
||||
|
||||
### Basic capture from IDS uEye camera
|
||||
```bash
|
||||
```powershell
|
||||
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
|
||||
```powershell
|
||||
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

||||
### Additional rollingsum examples
|
||||
|
||||
Analyze column 320 with larger window:
|
||||
```bash
|
||||
```powershell
|
||||
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=5000 column-index=320 threshold=0.3 ! queue ! autovideosink
|
||||
```
|
||||
|
||||
Use stride for faster processing (sample every 2 rows):
|
||||
```bash
|
||||
```powershell
|
||||
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 stride=2 threshold=0.5 ! queue ! autovideosink
|
||||
```
|
||||
|
||||
Lower threshold for more sensitive detection:
|
||||
```bash
|
||||
```powershell
|
||||
gst-launch-1.0 idsueyesrc config-file=ini/whole-presacler64_autoexp-binningx2.ini exposure=0.5 ! videoconvert ! video/x-raw,format=GRAY8 ! rollingsum threshold=0.2 ! queue ! autovideosink
