Matlab：原始图像DNG BitsPerSample 10不支持

Question

正如Steve Eddin在http://blogs.mathworks.com/steve/2011/03/08/tips-for-reading-a-camera-raw-file-into-matlab/中发表的那样，我跟随并复制了下面的代码，在MATLAB 2014b中运行。结果，我收到以下错误。＆＃34;不支持读取BitsPerSample为10的图像＆＃34;。我检查了info和info.SubIFDs {1}，我在INFOS中得到了以下结果。我在谷歌上搜索了这个问题，但没有足够的信息。因此，我在这里发布了这个问题，并希望有人给我解决方案。

CODE ::

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);

ERROR ::

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);

                [varargout{:}] = obj.readAllStrips();
