Problems of BlazePalm's recognition accuracy and operation performance

[ghost]

Hello, I tried to run BlazePalm on iPhone 7 and found 2 problems:

1. The detection accuracy of BlackePalm for hand key points is worse than that of MediaPipe Hands, which sometimes leads to false recognition.
2. MediaPipe Hands on iPhone 7 can run at a performance close to 30FPS, but BlackePalm seems to have less than 15FPS. Can the above problems be optimized? Is there a solution? be deeply grateful!
