I have an image (medical image) stocked as .TIFF file, when I read it I’ve found 4 matrix the first, the second and the third one are the RGB components of my image the fourth one is a binary matrix (contains only 1 values), I dont know what is it. I’ve denoised it but the problem is : -when I save it I got 000 values (black image) but when I open it under matlab I see that it is not an empty matrix this is my code :
t = Tiff([source2,'',num2str(v)],'w');
tagstruct.ImageLength = 1000;
tagstruct.ImageWidth = 1024;
tagstruct.Photometric = Tiff.Photometric.RGB;
tagstruct.BitsPerSample = 32;
tagstruct.SamplesPerPixel = 4;
tagstruct.RowsPerStrip = 1000;
tagstruct.ExtraSamples =Tiff.ExtraSamples.AssociatedAlpha;
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
tagstruct.Software = 'MATLAB';
tagstruct.SampleFormat=Tiff.SampleFormat.IEEEFP;
t.setTag(tagstruct);
t.write(single(Iy_d));
t.close();
I want to read the head of the file in order to check my BitsPerSample but I couldn’t
Xn= imread([source,'', num2str(v)],'tif')
I got this error :
info = imfinfo(Xn);
Error using imfinfo (line 80)
Expected FILENAME to be one of these types:
char
Instead its type was uint8
this make me confused because it shouldn't be uint8 !, So I convert it to double
Xn=im2double(imread([source,'', num2str(v)],'tif'))
But without any avail

imfinfo needs to be applied to the image file name, not to what was read in from the file.
