如何在使用TensorFlow的网络摄像头检测到的图像上不显示分数

标签: python tensorflow

我正在使用的代码的URL为: https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/camera.html

在此代码中,当检测到物体时会附加分数。我不希望分数出现在图像上。但是标签应该在一定的分数阈值之后出现。我正在Windows 10上工作。仅必须显示框和标签,而不是分数。

    # All the results have been drawn on the frame, so it's time to display it.
    cv2.imshow('Object detector', frame)

    # Press 'q' to quit
    if cv2.waitKey(1) == ord('q'):
        break

# Clean up
video.release()
