------------------------------------------------------------------- Fri May 6 17:54:07 UTC 2022 - Atri Bhattacharya <badshah400@gmail.com> - Update to version 2.14.0: * The following functions are new: affine, affine2d, affine3d, imapplymatrix, imfuse, imshowpair. * New features "anti-aliasing" and "custum kernel" were added to imresize. New method "box" was also added. * Inaccuracies in imresize bilinear interpolation and in bicubic interpolation were fixed, making imresize much more compatible with Matlab. * The function grayslice returns different results on input images of class int16. * Other functions that have been changed for smaller bugfixes, increased Matlab compatibility, or performance: psf2otf, imtransform. ------------------------------------------------------------------- Sun Feb 9 07:03:22 UTC 2020 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 2.12.0: * The following functions are new: imref2d integralImage integralImage3 imref3d * Improved the cubic interpolation method in imremap. This should also cause improved results in the functions imperspectivewarp, imresize, and imrotate when using the cubic or bicubic methods. * The function labelmatrix was changed for compatibility with the upcoming Octave version 6. * The function bwmorph now supports the "endpoints" operation. * The function nonmax_supress was renamed nonmax_suppress to fix its incorrect spelling. The incorrectly named function is kept for backwards compatibility. * The functions imremap, imperspectivewrap, and imrotate no longer return the `valid' output argument. * The imgradientxy function will now recognize the methods "central" and "intermediate" for Matlab compatibility. Their previous names "centraldifference" and "intermediatedifference" continue to work for backwards compatibility. * The stdfilt function will again handle all images of non floating type (a regression introduced in the version 2.10.0). ------------------------------------------------------------------- Mon Jan 14 14:00:30 UTC 2019 - hiwatari.seiji@gmail.com - Update to version 2.10.0: * The following functions are new: axes2pix, colorangle, houghpeaks bwpack, deconvwnr, otsuthresh, bwunpack, houghlines * The functions entropyfilt, rangefilt, and stdfilt were completely incorrect and have now been fixed. * In function regionprops, "Perimeter" was changed to be compatible with Matlab, and "PerimterOld" was added. * In function regionprops, properties "ConvexHull", "ConvexImage", "ConvexArea", and "Solidity" were added. * In function bwfill, the parameter connectivity was changed to be Matlab compatible. * grayslice now expects argument V to be a vector with the actual values used to perform threshold. * The function operation "thin" in bwmorph was changed to be Matlab compatible. * imcast now also converts images to logical type. * wiener2 is now able to handle images with arbitrary number of dimensions. * Other functions that have been changed for smaller bugfixes, increased Matlab compatibility, or performance: bwdist, entropy hough_line, bwmorph, graythresh Read /usr/share/octave/packages/image-2.10.0/packinfo/NEWS for more details ------------------------------------------------------------------- Wed Nov 21 10:59:46 UTC 2018 - badshah400@gmail.com - Update to version 2.8.1: * Fix imcrop for non-square images, a regression introduced in version 2.8.0. ------------------------------------------------------------------- Wed Jul 18 07:42:49 UTC 2018 - badshah400@gmail.com - Update to version 2.8.0: * The following functions are new: hough, imhmax, ntsc2rgb, imextendedmax, imhmin, rgb2ntsc, imextendedmin, imimposemin, viscircles, imfindcircles, imsharpen, wiener2. * Octave version 4.0 is no longer supported. This makes Octave version 4.2.0 the minimum requirement. * The functions ntsc2rgb and rgb2ntsc have been removed in Octave core version 4.4 and are now part of the image package. In a similar manner, rgb2gray, which has always been part of the image package, is part of Octave core version 4.4. The versions in the image package will only be installed if they are missing from Octave to avoid shadowing the core functions. * imcrop will now adjust the region to crop to the image boundaries when the region to crop goes beyond the image boundaries. * ycbcr2rgb, rgb2ycbcr, and rgb2gray will return an image of class single if the input was class single (they were previously returning a double for such cases). * The function imdither has been removed. This function hadn't work since Octave version 3.8.0 and would need to be rewritten. The function dither from Octave core should be used instead but hasn't been implemented yet. Instead of rewriting imdither, the missing dither function should be written. See bug #41768. * graythresh will now clip values outside the [0 1] range in images of floating point class. A side effect of this is that it will no longer distinguish between an image of floating point class that has only one one row or column, and an histogram. Breaks backwards compatibility if you were previously relying on something like 'graythresh (img(:), ...)' and img is of class single or double. * Fix regionprops Perimeter when using a labelled image or a bwconncomp structure, from connectivity different from 8. * The functions ycbcr2rgb and rgb2ycbcr now support conversion according to the BT.2020 standard. * Other functions that have been changed for smaller bugfixes, increased Matlab compatibility, or performance: bwperim, imlincomb, imrotate, entropy, imreconstruct, normxcorr2, graythresh, imregionalmax, phantom, imhist, imregionalmin, rgb2gray. - Update (Build)Requires: octave >= 4.2.0 now required. ------------------------------------------------------------------- Thu Nov 24 13:11:20 UTC 2016 - dmitry_r@opensuse.org - Update to version 2.6.1 * New functions. * Better MATLAB compatibility. ------------------------------------------------------------------- Thu Aug 13 10:31:19 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.4.1 * Bugfix release - Drop ovsolete workaround_gcc_65843.patch ------------------------------------------------------------------- Sat Jun 20 08:22:07 UTC 2015 - dmitry_r@opensuse.org - Fix build with GCC5 * workaround_gcc_65843.patch ------------------------------------------------------------------- Wed Apr 8 08:11:02 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.4.0 * The following functions are new: bwareafilt imcast imregionalmin bwpropfilt imclearborder otf2psf edgetaper immse psf2otf fftconvn imreconstruct psnr imattributes imregionalmax subimage * The implementation of normxcorr2 has been changed. The new method is Matlab compatible and will return values in the range [-1 1]. * The image package is no longer dependent on the signal package. * The disk shaped filter of fspecial has been changed for Matlab compatibility. The elements on the border of the disk are now weighted by how much of them is covered by the disk. Note that this change is backwards incompatible. * The following functions will display the output image as a figure instead of printing to the command line, when there are no output arguments: grayslice im2bw * For better compatibility with Matlab, the imrotate, imremap, and imperspectivewarp functions now use 0 instead of NA for the default extrapolation value. * The regionprops function now supports the "Eccentricity", "MajorAxisLength", "MinorAxisLength", "EquivDiameter" and "Extrema" properties. The "Orientation" property has also been rewritten for Matlab compatibility and may yield different results than previous versions. * The conndef function has new function signatures so that it covers all common ways of defining an connectivity array. * Creating disk shaped strel objects must now specify the N argument for number of periodic lines used to approximate a disk. The value used must be zero to obtain the same results as previous releases of the image package. No other value is at the moment valid, and this is to prevent future backwards incompatibility since Matlab default is 4. Replace any `strel ("disk", radius)' with `strel ("disk", radius, 0)' * The following functions have been completely rewritten and will perform a lot of faster. bwconncomp bwlabeln Which indirectly will also cause the following to perform faster: bwareaopen bwpropfilt regionprops * Deprecated functions. The following functions were deprecated in image 2.2.0 and have been removed from image 2.4.0. bwborder iptchecknargin readexif impad iptcheckstrs imrotate_Fourier uintlut * Other functions that have been changed for smaller bugfixes, increased Matlab compatibility, or performance: grayslice im2single imsmooth im2double im2uint8 label2rgb im2int16 im2uint16 ------------------------------------------------------------------- Thu Feb 26 16:06:43 UTC 2015 - dmitry_r@opensuse.org - Split from octave-forge package, version 2.2.2
