#42You can also apply this to each frame in a video for a rather interesting effect. My brother has a YouTube channel full of content-aware scaling videos: https://youtu.be/a8k3b-QNbhs
Really cool. Do you know what he’s using to do the scaling?

Oh that's horrifying/skin-crawling. I don't know what's wrong with me, but I can't stand to watch it. :)

Wow, that's incredibly interesting! My first reaction is how actor's faces look surprisingly like traditional caricatures that illustrators do -- e.g. shrinking foreheads and chins which are detail-light but keeping eyes and ears which are detail-heavy. But my second thought is that the extreme jumpiness in frames occurs because each frame is processed separately. But if you considered each seam not to be a "jagged l…
That's quite an insight!
Actually the authors of the seam carving paper went on to do just that [0]. From the abstract: "We present video retargeting using an improved seam carving operator. Instead of removing 1D seams from 2D images we remove 2D seam manifolds from 3D space-time volumes. To achieve this we replace the dynamic programming method of seam carving with graph cuts that are suitable for 3D volumes."

Very interesting, but it is hard to watch for me because of extreme shaking. Maybe some morphing would smooth the transitions.

#46Unsurprisingly it fails when there are no low-risk paths: https://i.imgur.com/58d5AFM.png
Brilliant implementation anyway. Having a lot of fun!
Re: Content-aware image resizing in JavaScript
#47Totally unrelated to this great project, but I'm curious: do people really use content-aware resizing feature in practice? I use Photoshop frequently, and I use content-aware removal A LOT (super handy). But it never occured to me, not even once, that I need to use the content-aware resizing despite it's there for years. If I really need to change the ratio of an image/photo I usually just crop.
Now that I am aware it exists, I can use it for blog headers where I'd like to maintain the same ratio, this would be needed for images that have details around the edges I don't want to lose.

Damn that's trippy

In the video comments he includes a link to a tutorial but essentially he is dumping all the frames and then running a script to content aware scale down the frames 50% and then merges it all back together.

>You might need to build a bit more flexibility into it to allow for discontinuities generated from object movement and camera panning, but I wonder if anyone's tried to do something like that?
easier solution would probably be frame interpolation between the two seperate frames.
