Motion Amplification and Video Magnification are techniques that find subtle changes in a video that are invisible to the naked eye and amplify them so they become visible. They have huge diagnostic potential in industry and medicine.

Video motion amplification: It's great when you want to give your boss a heart attack!!!

The most important thing I've taken away from this is that, really, I should get paid by Google every time I prove I'm not a robot.

I'm an audio engineer and I find this to be really interesting because I could possibly use it to see how different materials resonate within a room and be able to spot problematic areas

As someone who's don factory work, those clips look terrifying.

that effect to visualize the vibration is trippy as balls

7:20, reminds me of the captcha minesweeper xkcd comic. āTo proceed, click all the pictures of mines.ā āThis data is actually going into improving our self-driving car project, so hurry-upāitās almost at the minefield.ā (# 2496)

1:32 "One [sensor] for each pixel" was probably correct. There are usually only as many sensors as there are pixels (even though each sensor only detects one color, whereas each pixel is composed of 3 colors). The sensors are arranged in a Bayer pattern (wherein there are twice as many green sensors as either red or blue) and a "debayering" process is used to construct each RGB pixel centered on each sensor location (using information from a small neighborhood of sensors).

I worked as a Vibration Analyst for almost 12 years. We could profile a machine's movement using a series of acceletometers and graphically depict the directionality, amplitude(severity), and frequencies(potential sources and/or resonance). But the linear graphs left a lot to the imagination for those with little or no experience in Vibration Analysis. Motion Amplification painted crystal clear picture that our managers could easily understand and helped motivate some much needed preventive maintenance. It was an amazing experience working with this technology!!!

I've used strobes before to detect cracks and misalignments in factory equipment. Use a variable strobe that you dial to a particular frequency based on the motor and drive speed. When you get to around the right frequency everything looks like it's in slow motion and cracks or loose stuff is easily visible. That amplification looks really useful for large areas though! Good stuff!

I've used Strobe Lights (timing lights) to visibly see the vibrations. Items were failing for customers and I used the strobe to detect the failure mode and make changes. This would only work for items that are vibrating at a given frequency. If it is random vibrations then you can't detect those with a strobe.

1:30 One for each pixel is actually correct. Color in color images is usually interpolated for each pixel (element in the processed image file) over several colored subpixels (actual sensor elements) so that you get about the same number of both (some are cut off at the corners of the image).

"Started out as an astronomer, wanted to be an astronomer, but I had a conversation with my advisor about being gainfully employed."

Interesting.
btw typical image sensors only have one photosite per pixel, the 3 color channels are deduced from neighboring pixels that are RGB filtered in a pattern. called bayer mosaic.

When you said "Phase variation of a complex steerable pyramid" and then proceeded to show a pyramid with a steering wheel, you definitely got my sub and a like š¤£
The videos you're making are informative, intelligent, and quite literally some of the most interesting and thought provoking subjects I've ever run across.
Telling everyone I know about this channel... you deserve so much more exposure for your work than you receive.

Great sense of humor (7:05) especially regarding "real time" autonomous vehicle decisions. I teach middle school and seeing who reacts to bizarre statements is a great way to see who is really listening.

I never thought I would see that here

As someone who works in an industrial setting this blew my mind. The safety applications are immediately obvious. I have 50 tanks on my site like the one in the first seconds of this video.

No lie, this is 100% what stuff looks like while trippin' on acid/mushrooms. (Everything is not in black and white, but the way you perceive things really looks like this motion amplification)

I like how this guy has a full wall in his library of National Geographic magazines, for a kid fascinated with NGm this is a dream come true.
