<\/a><\/p>\nFor this project, I learned the difficulties of chroma detecting. I was trying to create a patch that would play a certain song every time the die (a Rubik’s cube) landed on a certain color. Since this computer vision logic depends highly on lighting I trying to work in the same space (spiking the table and camera) so that my color ranges would be specific enough to achieve my goal. With Oded’s guidance, I decided to use a Simultaneity actor that would detect the Inside Ranges of two different chroma values through the Color Measure actor, which was connected to a Video In Watcher. I duplicated this set up six times, trying to use the most meaningful RGB color combinations for each side of the Rubik’s cube. The Simultaneity actor was plugged into a Trigger Value that triggered the songs through a Movie Player and Projector. Later in the process I wanted to use just specific parts of songs since I figured there would not be a lot of time between dice roles and I should put the meaning or connection up front. I did not have enough time to figure out multiple video players and toggles and I did not have time to edit the music outside of Isadora either, so I picked a place to start that worked relatively well with each song to get the point across. However, this was more changing when wrong colors were triggering songs. I feel like a little panache was lost by the system’s malfunction, but I think the struggle was mostly with the Webcam’s consistent refocusing – causing the use of larger ranges. I am also wondering if a white background might have worked better lighting wise. (Putting breaks of silence between the songs may have also been helpful to people’s processing of the connections btw colors and songs). Still, I think people had a relatively good time. I had also wanted the video of the die to spin when a song was played, but with readjusting the numbers for lighting conditions, which was done with Min\/Max Value Holds to detect the range numbers, was enough to keep me busy. I chose not to write in my notebook in the dark and do not aurally process well, so I am not remembering other’s comments.
\nHere are the songs: (I trying to go for different genres and good songs)
\nBlue – Am I blue?- Billie Holiday
\nRed – Light My Fire – Live Extended Version. The Doors
\nGreen – Paperbond- Wiz Khalifa
\nOrange – House of the Rising Sun- The Animals
\nWhite – Floating Away – Chill Beats Mix- compiled by Fluidify
\nYellow – My girl- The Temptations<\/p>\n
Also, Rubik’s Cube chroma detection is not a good idea for use in automating vehicles.
