Image Sequencer is an online tool for image processing -- based on the idea of a storyboard. Each modification makes a new copy of the image, resulting in a series of images showing each step. It is designed for use in browsers, as well as on the Raspberry Pi. This project is supported in part by the NASA AREN project
Image Sequencer is different from other image processing systems in that it's non-destructive: instead of modifying the original image, it creates a new image at each step in a sequence. This is because it:
- produces a legible trail of operations, to "show your work" for evidential, educational, or reproducibility reasons
- makes the creation of new tools or "modules" simpler -- each must accept an input image, and produce an output image
- allows many images to be run through the same sequence of steps - batch processing
- works identically in the browser, on Node.js, and on the command line

There's now an "NDVI" feature in MapKnitter -- a beta -- for converting the images you upload with the #NDVI equation. It's set up for red filters only right now, but more will come.
It uses Image Sequencer to do the conversion, which is temporary - your map is not affected, so think of it as a "filter" you can turn on.
