R2011a
9-2
New bwconvhull Function Computes Convex Hull Image
Use bwconvhull to compute the convex hull image from a binary image.
New dicomwrite Option Writes Multiframe Imagery to Single File
Set the new 'MultiframeSingleFile' option of the dicomwrite function to true to
write multiframe imagery to one file, regardless of how many frames the input image
contains.
nitfread Now Reads NITF Files with JPEG-Compressed Images
If you have NITF files containing JPEG-compressed images, you can now read them
using nitfread.
Reduced Memory Use for std2
The std2 function has improved performance for large 1-, 8-, and 16-bit integers.
Compatibility Considerations
Compared to releases before R2011a, the std2 function now returns slightly different
results for some images. To receive the same results as previously, use this code:
% For input image im
if ~isa(im,'double')
im = double(im);
end
std_old = std(im(:));
Reduced Memory Use for watershed
The watershed function is now more memory efficient than it was in releases before
R2011a.
Compatibility Considerations
The watershed regions in the label matrix returned by watershed have different indices
than they did before R2011a.
