[SIP-devel] New! SIP 0.2.0 (for linux/unix)

[Ricardo F. <rf...@if...>]

The Cybernetic Vision Research Group and its collaborators
announces the new version 0.2.0 of SIP, the Scilab Image Processing toolbox=
=2E

Binaries for Linux are available for use with both Scilab 2.6 and 2.7.
They are self-contained, meaning that there is no need to download ImageMag=
ick.
The user just needs to execute the loader.sce script.  ImageMagick is only
needed if the user installs SIP from sourcecode.

SIP 0.2.0 should be easily portable to most Unix-like systems, as it now us=
es
autoconf, automake and libtool for the build process.

*** NOTE: No windows binary is available yet (volunteers are needed!)


What's New
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There are major enhacements in this release, as summarized bellow:

   o New mogrify command (resizing, rotating, filtering, etc)
   o New state-of-the-art O(n) skeletonization algorithm based
     on the euclidean metric, implemented in C and accessible
     through the scilab function "skel".  It has a multiscale
     pruning parameter.
   o Fast euclidean distance transform and discrete Voronoi
     diagram calculated by the same algorithm.
   o New xgetpixel command to get pixel coordinates from mouse
     position
   o New edilate command to do exact euclidean dilation
   o New percol command to check for image percolation
   o New drawline command to draw a line in an image
   o New perim function (perimeter measure of a shape)
   o minmax - new min/max noise removal from images (by curvature/levelsets=
)
   o New Hough transform (early working implementation)
   o Early fractal dimension implementation
   o Curvature/ffteriv/gsm/gsm2d rewrite
   o Curvature2d - estimates the curvature of a surface / image
   o Improfile - plot data profiles along line segments through an image
   o Imshow is now faster for truecolor images.
   o Adaptive thresholding though the mogrify parameter "-lat". This
     requires ImageMagick 5.5.2 or later.
=09o New edge-detection by FFT gradient estimation; this
=09  is available in the =E9dge' routine, by giving an 'fftderiv' value
     for the method argument.
   o New masks for mkfilter - laplacian masks, low-pass masks, sharp
     masks, mean, and circular.
   o New unwrapl function - unwraps phased images linearly
   o Imshow has new strf parameter
   o Imshow is now faster for truecolor images.
   o No more need to normalize truecolor images to 0-65535 range
     for imshow. This means you can now call imshow(im),
     and _not_ imshow(im*65535), if 0 <=3D im(i,j,k) <=3D 255
   o No more need to fix Scilab makefile bugs to compile SIP. The
     build process is now based on autoconf, which means the user
     types "configure; make; make install" to compile SIP (only
     POSIX-like environments are supported).
   o A "hello_sip" function added as a simple example, for new
     developers, of how to add a new C-language routine to SIP.
   o The general purpose C routines were moved to AnImaL (An Imaging
     Library), which is independent of Scilab.
   o Many bugfixes


SIP is primarily developed by Ricardo Fabbri <rf...@if...>.
Special thanks goes to Jocelyn Druel, Leandro Estrozi and Bruno Pincon for
their valuable contributions!

I hope you enjoy SIP 0.2.0
and consider contributing!
Ricardo.
