The PPT file of the slides is available: click here.
 

Sources + Binaries

Note: the binaries are a bit old; you may use the source C for our TPAMI'04 paper, which was an extension of my CVPR'01 paper: click here.

The gzipped binary (Linux) is available: click here (10,590 Ko, yes !).

Running psis is quite easy: simply unzip the file is necessary (gzip -d psis.gz), and then run it !
Psis runs on the command line, as for example:
The program options (-S, -B, -P) are options for formatting the output images of the segmentation. There is also a very, very slight help (the full help did not fit into the 22 Ko program :-)), which you can obtain by running:
The program runs using the same parameters as in all experiments (here, in the procs, in the draft). We refer the reader to the CVPR paper.
The experiments of this webpage displays some experiments, the tiff source images of which are available, if you want to give psis a try :-).
Note that psis is implemented to work on tiff RGB (color 8-bits uncompressed) images.
 

Experiments

The following tables display the result of the algorithm PSIS on various images, represented with their original size. The tiff images that were used to obtain the results are also available.
