I'm a Ruby newbie - "Programming Ruby" was great Xmas break reading! I write image analysis and processing code to analyze single cells under a microscope in real-time and to automate lab equipment. I now write solely in C++ for PC, but I would love to use Ruby to quickly try new ideas without plowing through C++ code. I have read through the forums and I see Ara Howard is using C extensions to process images - I'll try the same thing. I have some questions for the group: - I capture images from a camera, process and analyze them, and display them at ~10 fps. Ruby-v4l (capture) is for Linux only. Tk is probably too slow, and someone recommended using OpenGL for display. Has anyone had success with image capture or display using Ruby? What worked? Any advice? - Is anyone using pure Ruby to process images real-time? RMagick is too limited for my applications. I doubt Ruby would match the speed of C, but it might be fun to try.
