The OWLv2 implements a wrapper for the OWLv2 model, which detects objects in RGB images based on a text prompt.

​
class OWLv2()
​
use_local
boolean
default:
"False"

If True, inference call is run on the local VM, else offloaded onto GRID-Cortex. Defaults to False.

​
box_threshold
float
default:
"0.4"

Confidence threshold for bounding box detection.

​
def run()
​
rgbimage
np.ndarray
required

The input RGB image of shape (M,N,3)(M,N,3).

​
prompt
str
required

Text prompt for object detection. Multiple prompts can be separated by a ”,”.

​
Returns
List[float], List[float], List[str]

Returns three lists: bounding boxes coordinates, confidence scores, and label strings.
