    Args:
        det_predictor: detection module
        reco_predictor: recognition module
        assume_straight_pages: if True, speeds up the inference by assuming you only pass straight pages
            without rotated textual elements.
        straighten_pages: if True, estimates the page general orientation based on the median line orientation.
            Then, rotates page before passing it to the deep learning modules. The final predictions will be remapped
            accordingly. Doing so will improve performances for documents with page-uniform rotations.
        detect_orientation: if True, the estimated general page orientation will be added to the predictions for each
            page. Doing so will slightly deteriorate the overall latency.
        detect_language: if True, the language prediction will be added to the predictions for each
            page. Doing so will slightly deteriorate the overall latency.
