Wall Advent Calendar 2023 Day 21 Whether preparing for a wedding, shaking off holiday pounds, or getting ready for summer, we often find ourselves wanting to lose around 3 kg (6-7 lbs) in a month.

For a more technical deep-dive, please refer to the foundational paper behind Stable Diffusion: (arXiv link) High-Resolution Image Synthesis with Latent Diffusion Models Images as Digital Data First, let’s look at how computers represent images as data. An image is an aggregation of pixels. A 1000 x 1000 image consists of 1,000,000 pixels. In standard digital imagery, each pixel is stored as an 8-bit integer (a number from 0 to 255), meaning any digital image is simply a collection of numerical values: ...
