PS: btw, pix_colorclassify actually does exactly what you want. It supports Greenish, Red-ish, Yellow-ish, Blue-ish, Black-ish and White-ish ;) And it has been extensively developed and tested using a large database of real colored paper photos under different<br>

illumination conditions. You may need a very recent GEM.<br clear="all"><br>Ricardo Fabbri<br>--<br>Linux registered user #175401<br><a href="http://www.lems.brown.edu/%7Erfabbri" target="_blank">www.lems.brown.edu/~rfabbri</a><br>

John Harrison posted on the Pd-list (not the Gem-dev-list) a nice approach in rgb. I&#39;ve incorporated them in the updated patches:<br>

&gt; hi!<br>
&gt;<br>
&gt; use pix_rgb2hsv to convert to hsv colorspace.<br>
&gt; then use pix_curve with 3 different tables for hue, saturation and value to filter out the desired color.<br>
&gt; then convert back with pix_hsv2rgb.<br>
&gt; it&#39;s a little bit of experimenting with the curves...<br>

&gt;&gt; Hi,<br>
&gt;&gt; I&#39;m trying to use some patches Max Neupert has published, to track motion. The patches use [pix_movement], [pix_background], [pix_blob] and other objects (not all of them in all the patches). I can track white for now fine, but can&#39;t really find out how to track green, for example (well, the actual color I want to track is greenish).<br>



&gt;&gt; Any suggestions on how to do this?<br>
