Yes, this will remain an open notebook. I'm scribbling: what if pixels were searchable? Metadata for pixels, some how auto-generated, or generated for 1 pixel according to the elements of its neighbors. You won't search for discrete images, but your search will turn up images in which a statistically significant number of pixels meet the criteria. Is this using a hammer to turn a screw, creating far more metadata than we can handle in order to execute jobs that could be done much more simply in another way?
