sam	53268650a7	* dbs.c: generate the initial halftone using random dithering instead of Floyd-Steinberg in order to avoid the energy level getting locally stuck around error diffusion structure artifacts. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2672 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
sam	18dd51e1a5	* Dithering algorithms no longer modify the original image. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2670 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
sam	41efcdecc0	* Prefix dithering functions with _dither_ to avoid namespace cluttering. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2666 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
sam	a6dcd80490	* dbs.c: optimise DBS by ignoring 16x16 cells that had no pixel changes for the last two iterations. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2664 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
sam	2a3c7ca990	* dbs.c: improve the DBS human visual system kernel by adding two Gaussian kernels. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2663 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
sam	628c2618da	* dbs.c: new dithering function: Direct Binary Search. One of the best dithering methods as of today, though extremely slow. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2651 92316355-f0b4-4df1-b90c-862c8a59935f	17 yıl önce
