matlab - Matlab を使用した Kinect の記録/再生 - 逆さまで、グレー スケールではなく白黒で

Question

画像処理プログラムのテストを容易にするために、xbox kinect から色ストリームと深度ストリームの両方を記録および再生するプログラムを作成しようとしています。現在、一括処理が完了しており、カラー ストリームは正常に動作しています。ただし、深度ストリームに問題があります。

現在、深度ストリームは上下逆に再生され、白黒でのみ再生されます。これが当てはまる理由について、私は 3 つの考えを持っています: 1) 11 ビットから 8 ビットへの変換 2) Motion JPEG 2000 形式 (これまで使用されたことがない) 3) カラーマップが間違っている

以下は私が使用しているコードです。これをやろうとしているのは私だけではないと思うので、ウェブ上でこの特定のものを見つけることができなかったので、ポインタと助けをいただければ幸いです.
