Image Processing Toolbox Release Notes

Major Bug Fixes

The Image Processing Toolbox 4.2 includes the following bug fixes made since Version 4.1. If you are upgrading from a release earlier than Release 13 with Service Pack 1, then you should also see Major Bug Fixes of the Image Processing Toolbox 4.1 Release Notes.

• The bwdist function now produces correct results for very large images (such as 10000-by-5000).
• The dicomread function no longer produces the "Error using reshape" message when reading a DICOM file containing multiframe data and overlays stored in both the pixel data and in the metadata.
• The dicomwrite function can now correctly handle data attributes with multiple VMs (value multiplicity).
• The dicomwrite function now produces correct results for the RLE (run-length encoding) compression type when the number of bits per pixel is greater than 8.
• The im2col function, when called with the syntax im2col(1:N, [1 N]), now returns a column vector.
• The imview function, when called with the syntax imview(I,[]), where I is a constant image, no longer produces a warning message about a badly conditioned polynomial.
• The montage function no longer displays an extra blank row when displaying certain multiples of images.
• The poly2mask function no longer errors when trying to close certain polygons, specifically polygons where the last element of vector X doesn't match the first element, x(1) ~= x(end), and the last element of vector Y matches the first, y(1) == y(end), or vice versa.
• The stretchlim function now uses more bins to achieve better results for input images of class uint16 or double.
