Major Bug Fixes

The Image Processing Toolbox, Version 4.0, includes the following bug fixes.

Function
Fix

bwlabel
No longer produces a segmentation violation when called with an empty matrix.

cpselect

The Control Point Selection Tool no longer causes MATLAB to hang when invoked from within a script or GUI with the input or uiwait functions, which wait for users to complete the selection.

Point prediction in the Control-Point Selection Tool no longer fails with the error message "Attempt to reference field on non-structure array 'pickPair'."

dicomread
Now reads DICOM files that contain 1-bit overlay data.

imabsdiff, imadd, imdivide, imlincomb, imsubtract
The image arithmetic functions no longer error when called with logical inputs

imfill
Now fills hole pixels on the outer edge of an image that are not connected to the background because a non-default connectivity was specified.

imresize
The anti-aliasing filtering, applied by imresize when shrinking an image, no longer causes a narrow strip of dark pixels to appear around the edge of the image.

label2rgb
Now uses a new default colormap. The zero-color in the previous default colormap was the same as the last color in the colormap, with the result that the object labeled with the highest number could not be distinguished from the background.

radon
An off-by-one error in the calculation of the center pixel location for images with even dimensions has been fixed.

rgb2ind
No longer errors when passed an input image that contain only a single color.

strel
The syntax strel('ball', r, h, 0) returns an empty strel object instead of a degenerate ball structuring element with radius 0.

Function	Fix
`bwlabel`	No longer produces a segmentation violation when called with an empty matrix.
`cpselect`	The Control Point Selection Tool no longer causes MATLAB to hang when invoked from within a script or GUI with the `input` or `uiwait` functions, which wait for users to complete the selection. Point prediction in the Control-Point Selection Tool no longer fails with the error message "Attempt to reference field on non-structure array 'pickPair'."
`dicomread`	Now reads DICOM files that contain 1-bit overlay data.
`imabsdiff`, `imadd`, `imdivide`, `imlincomb`, `imsubtract`	The image arithmetic functions no longer error when called with logical inputs
`imfill`	Now fills hole pixels on the outer edge of an image that are not connected to the background because a non-default connectivity was specified.
`imresize`	The anti-aliasing filtering, applied by `imresize` when shrinking an image, no longer causes a narrow strip of dark pixels to appear around the edge of the image.
`label2rgb`	Now uses a new default colormap. The zero-color in the previous default colormap was the same as the last color in the colormap, with the result that the object labeled with the highest number could not be distinguished from the background.
`radon`	An off-by-one error in the calculation of the center pixel location for images with even dimensions has been fixed.
`rgb2ind`	No longer errors when passed an input image that contain only a single color.
`strel`	The syntax `strel('ball', r, h, 0)` returns an empty `strel` object instead of a degenerate ball structuring element with radius 0.
