Hi all, My name is Ding Jie, and Jenny is my English name. I'm a first-grade post-graduate student, major in Image Processing, and very interested in algorithms of this field. Thanks for neo's suggestion, I found SIOX is very interesting. I have read some paper about SIOX written by Gerald, and feel SIOX have potential to improve. Firstly, SIOX performs not good when dealing with gray images. Secondly, it isn't good at extracting things from a background whose color is similar to foreground. I'm wondering is it possible to use some new approaches side-by-side, and make the final output as the combination of all those approaches' output. My skill of programing: An experienced GNU/Linux user, skill in open source developing tools(gcc, gdb, svn, etc.), fluent C programing and Perl programing, and know some Python. A drawback is I have no GTK+ programing experience, but I believe it not be hard if I learn. :) Cheers, Jenny _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
