I have a code taken from internet
filename=Lenna.bmp
info=imfinfo(filename);
mingrayvalue=info.MinSampleValue;
maxgrayvalue=info.MaxSampleValue;
graynum=maxgrayvalue-mingrayvalue+1;
I get error
Reference to non-existent field 'MinSampleValue'.
Please provide assistance

imfinfo() only has 9 fields that are certain to be returned by every file format. MinSampleValue is not one of them. It appears that that field is returned for TIFF files but not for (e.g.) JPG files.

Does the reply of IMFINFO provide a field "MinSampleValue" for other pictures? See http://www.mathworks.com/help/techdoc/ref/imfinfo.html
