Thanks, I will also add it to fanres, later today. :-)

Here's the same comparison between sharpening, deblurring, and super resolution for the Obi-Wan frame I posted a while ago.

Now this is strange.

In the earlier comparisons this Obi-Wan cap looked like a standout moment where there were immediately noticeable gains. Now I can't see much. WTF?

@ zee944

The earlier comparison included a combination of super resolution and non-linear filtering (super resolution v8). This is the raw super resolution result that enhances detail, but also enhances noise (super resolution v3).

I've noticed it's not your full script, but I still expected to see the gains easily. Could you please post a comparison between the raw SR and your final result with the same frame?

@ zee944

The differences between the simple upscale and raw super resolution are still pretty easy to spot (at least to my eye). 

Update:

Here's the comparison between SR raw and SRV8:

update 2:

I now see it's not the same frame. It's difficult to see on my mobile. I used a different frame for the Team Blu comparisons than the ones I posted earlier.

Thanks.

I'm still surprised. Maybe it's the price you have to pay for a nice antialiasing (on Team Blu's work).

Maybe it's just because of the frame, or the difference of the frames, but the raw super resolution looks better to me than the current script. No kidding.

Due to the filtering a tiny amount of detail is lost. This frame always had a relatively small amount of visible grain due to the dark background. For light backgrounds the difference is pretty obvious though. I'll post an example later. 

 A really good example I saw was when R2 and C-3PO wake up in the Sandcrawler. Its quite dark, but the grain and noise is nowhere near as heavy as the desert scenes. This was just the raw GOUT, straight from the DVD.

Have you been, or will you ever be?

@ Zyrother

This is one of the challenges with this type of upscale. Some of the scenes are so grainy, the amount of detail enhancement is matched by an equal amount of grain amplification. The standard filters weren't quite up to par, so I wrote a non-linear filter that keeps as much of the detail, while removing the enhanced noise, and replacing it with a reduced GOUT grain.

@ DrDre

It seems like the most difficult thing is to create a script that gives consistent results across the entire film. Some areas may look fantastic, but others may not change that much, or in the worst case, actually look worse than before.

An exercise in patience is what it has come down too. :P

I think you guys have just about used up this thread's supply of unnecessary @ symbols.  I'll put in an order for more, but they probably won't arrive until next week...so try to be a little more judicious in using them.

You're absolutely right! Let's use 2 instead. :-P

I hope to get another video sample online this weekend. In the mean time here are a couple of screenshot comparisons for the sample. Notice the detail recovery for R2D2 in the first screenshot.

Update:

Here's a screenshot for one of the scenes I'm working on now:

This is a standout example of super resolution detail reconstruction, especially noticeable on C3PO.

This screenshot comparison shows very clearly that super resolution has some clear advantages over sharpening. In this case I used the sharpen filter in Virtualdub for the comparison. From this example is it very clear that compared to sharpening, super resolution has more detail, while having less noise enhancement, less ringing, and less aliasing.

So, unlike some critics stated in the past, super resolution does indeed enhance detail, while simultaneously reducing noise, ringing, and aliasing compared to standard enhancement techniques.

DrDre, two questions:

are you using some blurring in the first three comparisons at Post 592?

And, according to the fact that the first frame of "Star Wars" should be 711, could you state the frame number for each comparison?

If someone (me, in particulr) would like to compare his/her own upscale filter, it's difficult to spot each single frame everytime! (^^,)

Thanks!!!

I don't use any blurring. Super resolution V8 is a combination of a super resolution script and non-linear filter I wrote, combined with a anti-ringing filter.

The frames I used for the first three are: 17119, 22100, and 23755.

DrDre: I asked because I noted SR V8 is softer than previous versions, also softer than mine...

I think you're comparing the spline64's 23755 to your script's output.  SRv8's samples are less noisy and it has a shadow error that looks like interlacing.

Thanks happycube, you are right... going to upload the proper image, and just edited the previous message!
