Taking Photos With Scotch Tape Instead Of A Lens Typically, when we want to take images, we use an image sensor paired with some sort of lens assembly to make a picture that’s sharply in focus. However, [okooptics] is here to show us there’s another way—using Scotch tape in place of a typical lens element. If you just put Scotch tape over an image sensor without a lens, you’ll just get a blurry image, whatever you point it at. With the right algorithms, though, it’s possible to recover an image from that mess, using special “lensless imaging” techniques. In particular, [okooptics] shows how to recreate the so-called coded aperture techniques which were previously demonstrated in [Laura Waller]’s DiffuserCam paper. It’s complicated stuff, but the video does a great job of breaking down the optics into understandable chunks. Armed with a Raspberry Pi HQ camera covered in a small amount of Scotch and electrical tape, [okooptics] is able to reconstruct a viable image from what initially looks like a blurry mess of nothingness, with the aid of the right deconvolution maths. It’s all about understanding the point spread function of the tape versus a regular lens, and figuring out how to fight off noise when reconstructing the image. We’ve featured previous work from [okooptics] before, too, like this impressive demonstration of light transport and reconstruction. Video after the break.

Before caffeine, my brain works just like a beginner AI. Mostly confused. Always scanning.

A short (fun) article on computer vision.

The Convolution Operation The First Step Towards Understanding Convolution Neural Networks!

17) ✨ The End

If you’ve read this far… thank you! 🙏🙏
Hope this post cleared things up

If you want to read further about how the convolution operation works (1D, 2D, and etc), take a look at my latest blog post!

The convolution Operation!

Imagine passing a "filter" over data to extract specific features.

That's essentially what #Convolution does!

From sharpening images to understanding audio, this operation is everywhere.

Let's dive into the magic behind it👇

Scientific Notes on Power Electronics: Product and Convolution of Fourier Series Convolution is a remarkable property of the Fourier transform, often cited in the literature as the “faltung theorem”.
