-------------------------------------------------------------------------
** Multiple documentation fixes for compatibility with new versions of
Texinfo.
** Fix error with imcrop when image was all zeros.
** Fix endless loop in bwdist when using the quasi-euclidean method in
x86 systems.
Summary of important user-visible changes for image 2.2.1 (2014/03/08):
-------------------------------------------------------------------------
** imcrop had many alternative interfaces added for more flexibility.
Added support in the input for indexed images, figures handles,
N-dimensional images, and specific bounding box vector for a
non-interactive usage. Output can now also return the bounding box used
for the cropping in addition to the cropped image. It will no longer
loop forever until it gets two valid coordinates for the bounding box.
** Fixed bug in imcomplement to compute the complement of signed integers
correctly.
** Fix imrotate to handle RGB images.
** Fix regression in bwdist when calculating the closest pixel map.
Summary of important user-visible changes for image 2.2.0 (2014/01/08):
-------------------------------------------------------------------------
** The imerode and imdilate have been completely rewritten for increased
performance and many Matlab compatibility fixes. Performance gains between
1.5-30X have been demonstrated. Main compatibility changes include the
addition of the shape option, support for the strel class, and allowing
structuring elements and images of different classes. Non-flat grayscale
erosion and dilation has also been implemented by making use of the new
strel class.
** With the increased performance in imerode and imdilate, all other
functions that use them, such imopen and imclose, get an equivalent
performance boost.
** Most of bwmorph operations now support N dimensional images and have
increased performance. Other Matlab compatibility fixes have been
made such as displaying image when there's no output variable.
** The __spatial_filtering__ function has been mostly rewritten and
performs in approximattely 1/5 to 2/5 of the previous time, depending
on the filter. With this change, all functions dependent on it,
rangefilt, entropyfilt, ordfilt2/n, medfilt2/n, and stdfilt, will also
perform faster.
** The following functions are new:
bwareaopen impixel strel
checkerboard imtransform tformfwd
cp2tform intlut tforminv
findbounds labelmatrix ycbcr2rgb
imgradient maketform
imgradientxy montage
** The following functions have been moved from the Octave Forge Image package
to GNU Octave core:
cmpermute cmunique iscolormap rgbplot
** The following functions have been deprecated in the previous release
of the Image package and have now been removed:
blkproc bmpwrite dilate erode
** The following functions have been deprecated (see their help text
for the recommended alternatives):
bwborder imrotate_Fourier iptcheckstrs
impad iptchecknargin uintlut
** The functions im2col and col2im has been completely rewritten for massive
performace increase (increases greater than 500X have been observed, with
biggest differences for smaller blocks and sliding option), and support of
N-dimensional blocks and images.
** rgb2ycbcr was completely rewritten to accept images of other classes, and
colormaps. A new argument was implemented to convert the RGB values
according to different standards.
** The use of non logical matrices to specify the neighborhood for the medfilt2
function has been deprecated. Also, when using a vector to specify the size
of the neighborhood, the elements were swapped (first element is now the
number of rows and the second the number of columns).
** For consistency with other functions that allow specification of padding
values, the function padarray now accepts the string "zeros" as a valid
option.
** The plot produced by imhist is correctly scaled on the X axis so that the
colorbar corresponds to the actual intensity of the stems; the given
colormarp is used on the colorbar for indexed images; and the stems no
longer display the markers at their top. The Y axis is also adjusted in case
of peaks with high values that prevent a good overview of the histogram.
** The option to create poisson noise to an image has been added to imnoise.
** With the addition of the strel class, imdilate and imerode are able
to handle strel objects.
** The performance of imresize has been greatly improved when using the
nearest neighbor method for N or 1/N scale factors (e.g.: 2, 50, 1/4, 1/7).
** The imperspectivewarp, imremap, imresize, and imrotate functions will now
accept any interpolation method from the interp2 function thus extending
the available methods to "spline" and "pchip". This in addition to the
"bilinear" and "bicubic" methods (same as "linear" and "cubic" respectively)
which are kept for matlab compatibility. For the same reason, the
"triangle" method (interpolation kernel) has also been added (which is the
same as "linear" method).
** Bug fixes on the concavity, intermodes, maxlikelihood, and minimum methods
of graythresh.
** The bwdist function will now consider any non zero value as object pixels,
the class of the distance matrix has changed to single, and indexes an
uint dependent on the matrix size.
** The transform option of imtophat has been removed (it was deprecated
in version 2.0.0) in favour of using imbothat.
** The function bwconncomp now returns the indices for each element in each
object, no longer the indices for the elements in the object boundaries
only. The connectivity default was changed to 8.
** The original Shepp-Logan model in the function phantom as been changed to
return all values in the range [0 1] rather than [0 2] by changing the
intensity of the first ellipse from 2 to 1.
** Other functions that have been changed for smaller bugfixes, increased
Matlab compatibility, or performance:
bwlabel bwperim padarray
** The following functions now fully support matrices with an arbitrary
number of dimensions:
bestblk col2im im2col
bwconncomp colfilt nlfilter
Summary of important user-visible changes for image 2.0.0 (2012/11/08):
-------------------------------------------------------------------------
** The following functions are new:
analyze75info imabsdiff iptcheckconn
analyze75read imadd iptcheckmap
analyze75write imbothat iptchecknargin
blockproc imcrop iptcheckstrs
bwlabeln imdivide iptnum2ordinal
getrangefromclass imlincomb iscolormap
im2int16 immultiply normxcorr2
im2single imsubtract wavelength2rgb
** The following functions have been deprecated in previous releases
of the image package and have now been removed:
imginfo
** The function `deriche' has been removed.
** The complete set of functions to work with Analyze 7.5 files has been
implemented. See `analyze75info', `analyze75read' and `analyze75write'.
** `graythresh' can optionally accept an histogram rather than an image. This
allows for preprocessing of the histogram previous to an automatic threshold
selection.
** Otsu's method for automatic threshold selection (default for `graythresh')
has been completely rewritten and should perform faster. Now, it can also
return a second value representing the ``goodness'' of the computed
threshold value (within class variance).
** Alternative algorithms for automatic threshold have been implemented in
`graythresh' (thanks to Antti Niemistö for releasing HistThresh toolbox
http://www.cs.tut.fi/~ant/histthresh/ from where many were ported, under a
GPL license). Currently, the following algorithms have been implemented
(see graythresh for notes and references):
concavity MaxEntropy minimum Otsu
intermeans MaxLikelihood MinError percentile
intermodes mean moments
** The following functions have been deprecated (see their help text
for the recommended alternatives):
blkproc bmpwrite dilate erode
** With the new function `imbothat' the transform option of
`imtophat' has been deprecated.
** The following functions have had been changed for bug fixes and/or
improved matlab compatibility
bwarea imhist im2uint8 isind
bweuler imnoise im2uint16 mat2gray
bwfill conndef isbw rgb2gray
cmpermute im2bw isgray
cmunique im2double isrgb
** `bwarea' now supports all image classes and considers objects all non
zero pixels (not all pixels higher than zero).
** `rgb2gray' now also supports images of the class single and performs a
weighted conversion to keep the image luminance instead of a the mean
through each color.
** `im2bw' now supports input images of the int16 class and deals better with
RGB images since it uses `rgb2gray' internally (see changes to rgb2gray).
Threshold is performed on all values greater than value instead of greater
than or equal.
** `imhist' is much more compatible with matlab and among other changes,
it now uses the whole range of the class for the histogram rather than
the minimum and maximum of the input image and displays a colorbar under
the histogram.
** `isbw' now defines a black-and-white image as a binary non-sparse
matrix. This is compatible with matlab. To use the old behaviour,
use the new option for the call "isbw (img, "non-logical").
For backwards compatibility, if a non-logical matrix of 0 and 1 is
used as input, `isbw' will still return true but a warning will be
issued since this will deprecated later.
** `isgray' now also returns true for matrices of the int16 class.
** `isrgb' now returns false for logical matrix.
** `tiff_tag_read' had several bug fixes and can now check IFDs beyond
the first. It can also accept mutiple tag values and IFDs simultaneously
and return a matrix of the values found. Its documentation has been
expanded (as well as an explanation of TIFF structure on the source)
** For sake of matlab compatibility, the behaviour of `mat2gray' has been
greatly changed. Among the changes, it will no longer swap the minimum and
maximum options if the first is larger than the later. Instead, will return
the image complement after truncation. Also, when the maximum and minimum
values are equal, `mat2gray' will truncate all values between 0 and 1. See
the help text (or source) for a detailed description of cautions.
** `bwfill' was fixed to always returns a logical matrix.
** `imnoise' has been expanded to accept images of differente classes instead
of only double and single.
** The private function `__bwdist` has been renamed `__bwdist__`
** Package is now dependent on GNU Octave version 3.6.0 or later.
** Package is now dependent on the signal package version 1.2.0 or later.
** Package is no longer automatically loaded.

** NEWS below this point were written after their releases for history **
** purposes and extracted from the Octave Forge general NEWS. Previous to **
** the image package version 1.0.11, all Octave Forge packages would be **
** released at the same time. Previous to the package version 1.0.0 there **
** were monolithic releases with no actual packages. This means that some **
** releases actually had no changes in the image package itself or changes **
** were small compared to the whole Octave Forge project and so, not **
** mentioned on the NEWS file. Inspection of the actual log in the **
** repository should be used if exact details are required. **
