class savant.base.converter.BaseObjectModelOutputConverter(**kwargs)

Base object model output converter.

abstract __call__(*output_layers, model, roi)

Converts raw model output tensors to a numpy array that represents a list of detected bboxes in the format (class_id, confidence, xc, yc, width, height, [angle]) in absolute coordinates computed with ROI information.

Parameters:

• output_layers (ndarray) – Model output layer tensors

• model (ObjectModel) – Object model, required parameters: input tensor shape, maintain_aspect_ratio flag

• roi (Tuple[float, float, float, float]) – [top, left, width, height] of the rectangle on which the model infers

Returns:

BBox tensor (class_id, confidence, xc, yc, width, height, [angle]) offset by roi upper left and scaled by roi width and height

Return type:

ndarray
