Yesterday @ #MadeByGoogle we also announced the latest on the Super Res Zoom feature on #Pixel7Pro

It's a project my team's been involved in since '18. This year, our teams've made it so much more powerful. You can zoom up to 30x. Let me show you in a 🧵

That👆one was the ultra-wide lens (0.5x).

This 👇one starts at 1x and get closer....
And closer....
That's not close enough - let's get closer ...
we're almost there....
And finally we're at 30x hybrid optical/digital zoom, seeing the top of One World Trade Center miles away.

I hope this gives you an idea what the zoom experience looks like on #Pixel7Pro. You can see the whole sequence in an album:

Today we announced a new feature on Pixel 7/Pro and @GooglePhotos called "Unblur". It's the culmination of a year of intense work by our amazing teams. Here's a short thread about it

1/n
#MadeByGoogle #fixedonpixel #Pixel7 #PhotoUnblur
@GooglePixel_US

Last yr we brought two new editor functions to Google Photos: Denoise & Sharpen. These could improve the quality of most images that are mildly degraded. With Photo Unblur we raise the stakes in 2 ways:

First, we address blur & noise together w/ a single touch of a button.

2/n
Second, we're addressing much more challenging scenarios where degradations are not so mild. For any photo, new or old, captured on any camera, Photo Unblur identifies and removes significant motion blur, noise, compression artifacts, and mild out-of-focus blur.

Here's a neat trick to impress your friends
Let's say you have some curve with a random shape, possibly even self-intersecting. Can you measure its length?

This isn't just a parlor trick -- it has many practical applications. For example, the curve could be a strand of DNA
1/n
You can think of the curve as a collection of tiny segments of course. You can then measure each segment and add up the results.

OK, but you can go further and take the segments to be so small that they are almost like points. You can then add up the (red) "points".

2/n
In practice, this is not easier though. So we need a mechanism for doing this more conveniently. One way to do it is to drop lines that intersect with the shape and count the number of intersections. You can do this with a mesh too.

This is a story about a guy you might have heard of.

A guy who understood that our journeys here on earth are short. That we’re all passengers pitching downward into the night

Yet he gave us stories with hope; so we can get up and move forward, explore, & help each other

I've posted a couple of dozen technical threads in the last two years that have been popular. Here they are in a thread of threads, very roughly organized into related themes.

Let's start w/ little-known classic: mean & median within a standard deviation

Stein's lemma and characterization of the Gaussian

Tweedie's Formula

I grew up eating some amazing sandwiches like the Kalbas (beef Mortadella) & Sosis (fried sausage) in Tehran. These are a meal and a half.

There's a crazy variety of sandwiches around the world. I've come across some memorable ones🧵:

1/n
Medianoche (Cuba):

Roast pork, ham, mustard, Swiss cheese, and pickles served on sweet bread. It is so named because of the sandwich's popularity as a staple served in Havana's night clubs right around or after midnight.

2/n
Chip Butty (UK):

Filled with chips (thick-cut deep fried potato, not to be confused with thin-cut french fries), optionally eaten with condiments such as brown sauce, ketchup, mayonnaise, or malt vinegar.

Sequential estimators (eg Kalman Filter) are hard to grok especially when couched in vector language.

For intuition, one can start from very simple: consider just least-squares on a scalar A.

Say we have n=0:N-1 noisy (0-mean & iid) measurements of A

x(n) = A + w(n)

1/7🧵
The least-squares estimate of A is simply the average of the N data points x(0), ... , x(N-1) . Now suppose a new data point x(N) becomes available

We can find the LS estimate all over, but that's wasteful for both memory and compute. Much more efficiently, we can update:

2/7
It's neat to observe that in this simple case, the update equation shows that the "correction" term should go to zero as N→∞

The situation is quite similar if the noise variance σₙ² is different from sample to sample. We can still update the estimate just as well
