matlab - Matlab: Raw 画像 DNG BitsPerSample 10 はサポートされていません

Question

Steve Eddin がhttp://blogs.mathworks.com/steve/2011/03/08/tips-for-reading-a-camera-raw-file-into-matlab/に投稿したように、次のコードをたどってコピーしました。 MATLAB 2014b で実行されています。その結果、「BitsPerSample が 10 のイメージの読み取りはサポートされていません」というエラーが表示されました。info と info.SubIFDs{1} を確認したところ、INFOS で次の結果が得られました。Google で問題を検索しましたが、十分な情報がありません。したがって、私はこの問題をここに投稿し、誰かが私に解決策を教えてくれることを願っています.

コード：：

warning off MATLAB:tifflib:TIFFReadDirectory:libraryWarning
t = Tiff('Non-Invasive DNGs/WP_20150311_15_03_14_Raw__highres.dng','r');
offsets = getTag(t,'SubIFD');
setSubDirectory(t,offsets(1));
cfa = read(t);
close(t);

エラー：：

Error using Tiff.constructBlankOutputImage (line 2448)
Reading images with a BitsPerSample of 10 is not supported.

Error in Tiff/readAllStrips (line 2046)
            imageData = obj.constructBlankOutputImage(imageSize,bps,sampleFormat);

Error in Tiff/read (line 1507)
                [varargout{:}] = obj.readAllStrips();

Error in readDNG (line 11)
cfa = read(t);
