Androidスタジオcamera2ノイズ除去

私はアンドロイドスタジオのカメラで作業しています.YUV420_888はCamera2からImageReader経由で出力されています。問題は、私にこの奇妙な騒音が聞こえるか、それが何であれ呼び出されたことです。ここにはlinkの画像があります。近くを見ると、グレーの色合いが異なる6-7の円があります。私は白黒画像が必要なのでYチャンネルだけを使用し、Yチャンネルはまさにそれです。エッジ検出アルゴリズムとそれらの「円」との干渉がエッジ検出においてノイズとして表されるので、大きな問題である。また、サーフェスが平面の場合にのみ表示されます。誰が私にこれがなぜ起こり、どのようにそれを修正するのか教えてもらえますか？Androidスタジオcamera2ノイズ除去

編集：私はコードについて何か知っていました。これは私がcamera2を動かそうとした元のアプリケーションです。

を作り、残りの部分は同じです。私がこれを表示すると、あなたが写真上で見ることができますが、最初のプログラムでは、最初のプログラムのようにTextureViewにYUV420_888を直接表示すると、すべてが問題ありません。どんな考え？

それが原因お使いのカメラのハードウェアの制限に量子化ノイズである可能性があります。サーフェスが薄暗い場合は、自動的に明るさの調整やホワイトバランスを使用してシーンをより見やすくすることができます。カメラに調整可能な絞り、調整可能なシャッター、または高解像度ADCがない場合、「Y」値に整数係数（ピクセルごとに）を掛けるなどして、デジタルで調整を行います。したがって、量子化ノイズ。

AWB modeを調整すると、より良い結果が得られる場合があります。より良い照明が役立つかもしれません。または、エッジ検出アルゴリズムでしきい値を調整することもできます。

EDIT

はすぐにaddCallback()呼び出しの後surfaceHolder.setFormat(PixelFormat.RGBA_8888)への呼び出しを追加します。

これは、表面のデフォルトの内部フォーマットの結果であり、実際にはARGB_8888よりも小さいものでした。 S6でも起こった。

AWBモードを変更しようとしましたが、うまくいきません。私は私の電話（CM12モードでサムスン銀河S2）でこのコードを試した。また、私はカメラのための私のアプリを開くときは、画像がはるかに良いです。私のコードは、このコードに似ています。エッジに関する問題は、私が従いたいエッジは、それらのサークルと同じ派生を持つということです。 http://inducesmile.com/android/android-camera2-api-example-tutorial/ – Nikola010

カメラアプリと同じ品質を自分のソフトウェアから得ることができるはずです。あなたのイメージファイルのバイトを見ると、間違いなく量子化が行われていますが、その理由は分かりません。私はYUV420_888がかなり良く見えると思っていたでしょうが、おそらくキャプチャパイプラインはあなたをそこに連れていくためにいくつかの変換を行わなければならず、いくつかの情報は失われました。私は他の利用可能なフォーマットを試みます。エッジ検出アルゴリズムを実行することができないかもしれませんが、少なくともそれらがTextureViewでどのように見えるか見ることができます。 – greeble31

実際には、私は何かプログラムに間違っていたようですが、何も得られません。オリジナルのポストを編集してコードを追加します – Nikola010
