Constructing A Good Enough Color Space For Skin Tones

a day ago

Project aims to define a color space for inclusive skin tones in digital tools like character creators.
Methodology involves manually labeling skin colors, applying PCA to transform RGB to XYZ, then fitting spherical equations in TUV space.
The color picker has three adjustable components (T, U, V) corresponding to up/down, left/right, and cool/warm, derived from PCA.
R² parameter controls the radius of the sphere in TUV space, allowing adjustable variation while maintaining realism.
Limitations include subjective labeling, exclusion of health conditions, and display inconsistencies.
Social context: lighter skin tones have been historically prioritized; racism and colorism are addressed through referenced resources.
Future work includes improving data labeling, modeling conditions like jaundice, and optimizing equations for different contexts.

Inkling-Small is a general-purpose multimodal model that accepts text, image, and audio inputs and generates text outputs.
It can be used with libraries like Transformers, vLLM, SGLang, and Docker, as well as through APIs and third-party providers.
The model uses a 42-layer decoder-only transformer with a sparse Mixture-of-Experts (MoE) architecture, totaling 276B parameters but activating only 12B per token.

Blender 5.2 LTS introduces a new Mesh Bevel node in Geometry Nodes for detailed procedural control over edges or vertices.
New node-based dynamics with built-in effectors for gravity and surface collision, including a tag-based filtering system for geometry interaction.
A brand new procedural approach to physics for hair and cloth simulations using Geometry Nodes.

Scanning Herculaneum scrolls requires synchrotron X-ray micro-CT with careful tuning of voxel size, X-ray energy, and sample-detector distance to balance resolution and phase contrast.
Unwrapping involves surface localization, mesh tracing, and flattening; tools like GrowPatch, lasagna, and spiral fitting are used, but human correction is still needed for errors like holes, mergers, and sheet switches.
Ink recovery is challenging due to carbon ink on carbonized papyrus; models trained on fragments use pseudo-labeling and self-distillation, but generalization across scrolls remains a bottleneck.

Hyprland 0.55 introduces Lua configs, enabling Lua-based configuration with updated wiki guidance.
User-defined layouts via Layout API in Lua allow custom layouts per workspace or monitor.
Scrolling improvements include fullscreen window support and native trackpad gestures.
