Hybrid Detection

We also support hybrid control detection using both UIA and OmniParser-v2. This method is useful for detecting standard controls in the application using the UI Automation (UIA) framework, and for detecting custom controls in the application that may not be recognized by standard UIA methods. The visually detected controls are merged with the UIA controls by removing the duplicate controls based on IOU. We illustrate the hybrid control detection in the figure below:

Hybrid Control Detection

Configuration

Before using the hybrid control detection, you need to deploy and configure the OmniParser model. You can refer to the OmniParser deployment for more details.

To activate the icon control filtering, you need to set CONTROL_BACKEND to ["uia", "omniparser"] in the config_dev.yaml file.

CONTROL_BACKEND: ["uia", "omniparser"]

Reference

The following classes are used for visual control detection in OmniParser:

Bases: BasicGrounding

The OmniparserGrounding class is a subclass of BasicGrounding, which is used to represent the Omniparser grounding model.

parse_results(results, application_window=None)

Parse the grounding results string into a list of control elements infomation dictionaries.

Parameters:
  • results (List[Dict[str, Any]]) –

    The list of grounding results dictionaries from the grounding model.

  • application_window (UIAWrapper, default: None ) –

    The application window to get the absolute coordinates.

Returns:
  • List[Dict[str, Any]]

    The list of control elements information dictionaries, the dictionary should contain the following keys: { "control_type": The control type of the element, "name": The name of the element, "x0": The absolute left coordinate of the bounding box in integer, "y0": The absolute top coordinate of the bounding box in integer, "x1": The absolute right coordinate of the bounding box in integer, "y1": The absolute bottom coordinate of the bounding box in integer, }
