Hi!
I reseached a litle bit about it but couldn't find a macro to suit my needs and I'm not familiar to Java programming (well, in fact, to programing, at all). I plan to record pupilar constriction during 2-5 minutes upon light pulses. The idea is to find a macro or plugin that allows me to measure the pupilar radius or diameter or area. So, I suppose te macro should: -Allow me to convert a video recording into frames. (I suppose this can be done via virtualdub, but I'm not so sure that imageJ would be able to understand it). -Find two concentrical circles (pupil and iris) and meassure the one inside or the distance between both. -It should be able to write the pupilar values along with the corresponding time or frame values in a file. -The tool should be able to measure from color images obtained in standard light and infrared conditions(CCTV camera, not sure jet if it is black and white or green, but I suppose it could be converted easily). I know, I may be asking for to much. I pretend to use it in a publication about the correspondence of this pupilar constriction and a protein highly responsible of this activity, melanopsin. Having this tool would mean tons of flexibilty and saving numerous animal lifes. If somebody wants to join I can only offer appearing in the final publication. Thanks for your time and if someone wants to help, you are highly welcome: uo155943@uniovi.es |
Hi Feel,
What you are asking doesn't seem too hard to do at first glanced but a definitive answer will be much more reliable if we have access to a sample of your data.

Hi!
Thanks a lot for the quick response. I'm gonna be out for a week, as soon as I come back I'll post a video from human and mice eye recordings. I'm new to nabble, any recommendation on how to post the videos? Upload to mediafire or youtube? Thanks a lot to everyone. |
Hi Feel,
Youtube and other video sharing site will convert your file to flash and thus make it more complicated to analyse. Therefore it is better to for a regular web site (google sites) or a file sharing site (mediafire). -- Gabriel Lapointe, MSc. Laboratoire de Luc DesGroseillers, PhD.
