ori333 Posted December 18, 2016 Share Posted December 18, 2016 Hello UVP, I'm excited to join your community. I have always been interested in the perspective of the world through the eyes of animals which led me to UVP. Currently I'm working on an augmented reality project that will highlight what the human visible spectrum can't see. Attached is a demo image assuming one can't see red. Since I don't have any UV equipment (yet), I hope we can collaborate and discover something new in this world. Does anyone else here have similar interst or is interested in sending some files in my direction? ThanksValentin Link to comment
nfoto Posted December 18, 2016 Share Posted December 18, 2016 Hello and welcome to you :D We probably might be able to provide some footage for your project. I have shoot a few UV videos over the years, for example. Link to comment
Andrea B. Posted December 19, 2016 Share Posted December 19, 2016 Hello Valentin and welcome to UVP. We have had a lot of fun here on UVP attempting to model insect or animal vision for those critters who have UV visual receptors. If you use the search tag Insect Vision, then you will see a list of topics on that subject. It is not enough simply to replace red flowers with black flowers. One must consider whether the red flower reflects UV or absorbs UV. The bee (or other insects) will see those two types of red flower differently. Link to comment
ori333 Posted December 20, 2016 Author Share Posted December 20, 2016 Andrea and Bjørn, Thank you for the warm welcome. After looking at the Insect Vision tag, I see my work is cut out for me. It will be interesting to incorporate all this information into software. BestValentin Link to comment
ori333 Posted December 20, 2016 Author Share Posted December 20, 2016 Andrea and Bjørn, I'm currently looking for a few unmodified Visible and UV pairs that I can practice with. Do you have any links where I can download RAW files of the exact same shot with one taken with visible light and one with UV? Most of the images I find on the site are already modified, or the visible shot is not the same as the UV shot. Thank youValentin Link to comment
Andrea B. Posted December 20, 2016 Share Posted December 20, 2016 Valentin -- If you give me a day or so I will "liberate" some paired UV/Visible/IR photos for you to experiment with. I'm busy today with various domestic errands. Link to comment
ori333 Posted December 21, 2016 Author Share Posted December 21, 2016 Thank you. Looking forward to it. Link to comment
Andrea B. Posted December 22, 2016 Share Posted December 22, 2016 OK, I packed up a set of 3 raw landscape images, one Visible, one UV and one IR. If you would please send me a PM with your name, the purpose for which you will use the images and your email address, then I will create a License and email it to you together with the Dropbox URL where you can download the files. The PM button is in the upper right corner by your name. Click the envelope icon and select Compose New. Use "Andrea B." for the recipient's name. Link to comment
Shane Posted December 23, 2016 Share Posted December 23, 2016 Hi ValentinI am on Whidbey and may be able to help in some aspects. PM a contact number and we can talk. Link to comment
ori333 Posted December 26, 2016 Author Share Posted December 26, 2016 Andrea, Thank you for the photos. I'm able to read .nef files in my computer vision platform (openCV). No computer vision modification yet. Just opening the file, ready for CV magic. https://github.com/UVeyes/Colorblind_Cyclops/tree/flower-imagesCommit Title: Able to read .nef filesSHA: 081291d92169f3260d29e5f756890186853a6a64 Link to comment
ori333 Posted January 6, 2017 Author Share Posted January 6, 2017 Hello UVP group, Andrea has sent me some photos of flowers. I ran them through the algorithm, and got marginal results. Several false positives that are nothing more than shade. Looks like I got my work cut out for me. I'll be changing the contour detection methods. Best Link to comment
Andrea B. Posted January 6, 2017 Share Posted January 6, 2017 Thanks for the update, Valentin! Differentiating between shadow and UV-dark areas and shadowed UV-dark areas would be very tricky. Here's a chart I made for a yellow UV-bullseye flower:http://www.ultraviol...at-a-sunflower/ Here is my trichromatic bee-vision rendition of the bouquet. Special patterning was used for the "impossible" bee colours like UV-green. Link to comment
ori333 Posted March 7, 2020 Author Share Posted March 7, 2020 Hello, I'm relaunching this project. This time I have a few cameras from MaxMax and AR headsets (Realmax 100 and Hololens 2). If anyone is still interested please let me know. BestValentin Link to comment
Cadmium Posted March 7, 2020 Share Posted March 7, 2020 ori333, Have you ever tried TMSB? Ben made that program, he lives up by you.I just thought of his program when I saw your photos.https://www.beneaththewaves.net/Software/The_Mirrors_Surface_Breaks.html Link to comment
ori333 Posted March 8, 2020 Author Share Posted March 8, 2020 Hello Cadmium, Thank you! Andrea pointed me to Ben's work a while ago. It's on my short list of software to implement on the Hololens 2. Looks very good, and a few light-years beyond the chicken scratch I made 3 years ago. I recently moved to NJ so Ben may not be as close now as before :). Wish I knew before :) Link to comment
Cadmium Posted March 8, 2020 Share Posted March 8, 2020 It is pretty cool software, does a huge amount of things. generates more image version sets than you can imagine.Ben Lincoln is always happy to help. It isn't exactly easy to get set up, but he will help people do it gets too complicated. Link to comment
