updates- fruit project

by caudenri @ 9:16 pm 6 April 2010

So, first of all, I apologize for not being there on Monday to present this. To refresh your memory, I’m doing a project where I’m trying to take time-lapse photos of natural color processes (such as a banana turning brown), get the average color of each frame, and display the colors as a gradient.

I’m trying to work on little modules in Processing that would be inserted into a website where people could explore the colors and hopefully download color swatches.

Not sure if the embed option for applets is going to work but in any case here is the link to what I have so far:caryn-finalprojsketch

Haven’t quite figured out yet how to have the image display even when you’re not hovering over the bar…but that’s going to happen at some point. Hover over the gradient bar to see the image the color came from and the hex color.

I did a lot of experimentation with sampling different points in the pictures…and even with my better lighting and picture-taking circumstances, the colors still look muddy. I’m still trying some things, not sure what I’m doing wrong but I think part of it is that the colors are just going to look more intense when they’re in the context of a photo rather when the actual color is singled out artificially.

Here’s a mock-up of what I’m starting to think this could look like on the web (ideally)

    the canon hacking development kit might help stabilize your images (and can add a timelapse to the camera) if you can get your hands on a Canon Powershot.

  2. Notes from 2010/04/07


    — you don’t need to have FF at the beginning of every color hex code. FF is the alpha channel; it’s always FF (opaque) by default for every color.

    — you really need to work on getting better hardware. I can loan you a white-balancing-able analog video camera.

    — Some other kinds of stuff to scan: Potatoes, Blood (takes about 2 days to brown), Sunburn, Milk in Coffee, Copper patina, Flowers, Day-to-Night Sky (sunsets)

    — Export & load smaller images, you don’t need to load 320×240. Load a quicktime video instead of a sequence of frames.

    you could do the thing with flowers or celery where you put it in a vase with food coloring and see how long it takes to soak up the colored liquid and change colors

    If you can get your hands on a Canon Powershot:
    From what i understand, it is a temporary firmware hack (ie. you take it off your flash card and the hack goes away). This could help to get your stabalized images, and can add a timelapse option if your Powershot doesnt already do it.

    Also, maybe you could burn things in a pan. You could get a cheap pan at Salvation Army or Goodwill and carbonize pretty much anything without having to worry about your own cooking equipment.

    Another interesting one could be getting the palette of a mood ring.

    I have a Canon PowerShot! Let me know if you need to borrow it πŸ˜€

    I’ve got a slime mold that you can photograph.

    Would it be disingenuous to boost the saturation of th colors? They seem a little desaturated.

    Watermellon? http://www.youtube.com/watch?v=OA6v7BVBcEU

    Mold on bread?

    Pizza! http://www.istockphoto.com/stock-video-11905620-pizza-rot.php

    Rotting stuff: http://www.google.com/search?q=rot%20time%20lapse&um=1&ie=UTF-8&tbo=u&tbs=vid:1&sa=N&hl=en&tab=wv

    For some objects, maybe people might want to select the masking area from which you sample, like I think mangos have a lot of color variation (as opposed to having the mask area being the whole object)

    Artichokes are pretty weird too; they turn brown fast. Dead animal on ants. Worm on hot sidewalk. Raw egg.

    Your interface is very cute! I know you don’t have a large data set yet, but it would be cool if you could “search by fruit” for in the future when your data set may be much larger. Good job, though!

    Andy Warhol have a piece called oxidation…or pee on copper ..that gives great color

    try to get bread to mold, tea leaves changing water color, a photograph developing, polaroid?

    flower petals from the tree?γ€€or leaves.

    the project would work with sol’s gardern camera… if expanded to any color changing video…

    Making color palettes out of time lapse video is really interesting. It would be fantastic if you could open-source the project somehow so that people could just set up their camera and hit “go” and then upload their timelapse thing (video) to your website thing that you showed.
