`get_colors.py` functionality #1

Closed fredhohman closed 8 years ago

fredhohman commented 8 years ago

Currently get_colors.py gets most frequent pixel colors. Should this change to become the most "dominant" colors? E.g. what if an image was mostly shades of a single color, but had some part that was drastically different that draws a person's eye, however that region's colored pixel count could be small in comparison to the other shades.

Thoughts?

I agree that this could be helpful, especially in movie scenes where the color change can rely on a small bright point. We could have multiple color options to switch between: (1) most frequent colors (2) most contrastive colors (3) background colors, etc.

Sounds like a good idea. Now... any idea how to implement these? Without the frequency count we may lose the ability to rank colors. I suppose most contrastive would be more tractable.

ianbstewart commented 8 years ago

I guess for most contrastive you could get most frequent, then cluster on RGB similarities, then pull out the one or two colors that didn't get assigned a cluster. Not sure how tractable that is for thousands of frames, though.

Actually by removing the sorting lines of code we might get what we want... can try this later.

ianbstewart commented 8 years ago

OK. I think for the proposal we'll just need one kind of color viz but it's good to have other options to implement later.

Possibly relevant for this.
