Hacker News·31wapple/pico-banana-400k
Apple released Pico-Banana-400K, a dataset containing approximately 400,000 text-image-edit triplets for training text-guided image editing models. The dataset includes 257K single-turn examples, 56K preference learning samples, and 72K multi-turn conversations, covering 35 edit operations across 8 semantic categories. Built using Gemini-2.5-Flash for instruction generation and the Nano-Banana model for editing, each edit undergoes automated quality evaluation. Source images come from Open Images, with edits spanning object manipulation, scene composition, stylistic changes, and photometric adjustments. The dataset is available under CC BY-NC-ND 4.0 license for non-commercial research use.
selfh.st·24wBuilding Slink: Lessons from Creating a Self-Hosted Image Hosting Platform

Ars Technica·49wMIT student prints AI polymer masks to restore paintings in hours
MIT graduate student Alex Kachkine developed a revolutionary art restoration technique using AI-generated polymer films that can restore damaged paintings in hours instead of months. The method creates transparent masks with thousands of precisely color-matched regions that can be applied to artwork and removed when needed, making restoration reversible. An AI model identified damage patterns and generated over 57,000 different colors to restore a 15th-century painting with 5,612 damaged regions in just 3.5 hours. This approach could help make the 70% of institutional art collections currently hidden due to damage accessible to the public again.

It uses Intervention Image for file manipulations and offers a self-hosted alternative to external image processing services.
IEEE Spectrum·33wWhere Was This Photo Taken? AI Knows Instantly
Researchers developed a machine learning model that matches street-level photos to aerial images for geolocation with 97% accuracy in initial narrowing and 82% for exact location. The system uses deep cross-view hashing with vision transformers to convert images into unique numerical fingerprints, making it twice as fast and using one-third the memory of competing models. The approach could benefit navigation systems when GPS fails, emergency response, and defense applications, though it needs further testing for real-world challenges like seasonal variations and cloud cover.
Hacker News·30wzserge/grayskull: A tiny, dependency-free computer vision library in C for embedded systems, drones, and robotics.
Grayskull is a minimalist computer vision library for microcontrollers and resource-constrained devices. Written in pure C99 as a single header file under 1000 lines, it requires no dependencies or dynamic memory allocation. The library provides grayscale image operations including filtering (blur, Sobel edges), thresholding (Otsu, adaptive), morphology (erosion, dilation), connected components, perspective warping, FAST/ORB feature detection for object tracking, and LBP cascades for face/vehicle detection. It includes PGM file I/O and uses integer-based operations optimized for embedded systems.
