Summary of important user-visible changes for image 1.1.0: ------------------------------------------------------------------- ** The following functions are new: analyze75info analyze75read blockproc bwlabeln getrangefromclass im2int16 im2single imabsdiff imadd imbothat imcrop imdivide imlincomb immultiply imsubtract iptcheckconn iptcheckmap iptchecknargin iptcheckstrs iptnum2ordinal iscolormap normxcorr2 wavelength2rgb ** The following functions have been deprecated in previous releases of the image package and have now been removed: imginfo ** The function `graythresh' now returns a second value representing the ``goodness'' of the computed threshold value. ** 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 bweuler bwfill imhist conndef im2double im2uint8 im2uint16 isbw isgray isrgb isind mat2gray rgb2gray ** `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. ** `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. ** `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) ** Package is now dependent on GNU Octave version 3.6.0 or later. ** Package is no longer automatically loaded.
