Deciding overlay text legibility at ingest time instead of on device — four metrics measured side by side
Moving the question of whether text stays readable over a wallpaper out of the device and into the content pipeline. Four candidate metrics measured across 240 images, including what downscaled judging actually computes.
The same wallpaper appeared twice in my catalog — measuring perceptual hash thresholds across 324 images
Four approaches to image catalog deduplication measured end to end: SHA-256, dHash, a hue signature, and a block signature. dHash alone scored 0.9% precision. Here is why perceptual hashes collapse on smooth images, and how the ground truth turned out to be the thing that was wrong.
Fixing Stutter When a Rork Max SwiftUI Image Grid Scrolls
Measure why a Rork Max SwiftUI image grid stutters while scrolling, then fix it with ImageIO downsampling, off-main-thread decoding, and stable cells to cut real-device hitches.
Building an AI Photo Editor App with Rork — Filters, Background Removal, and Style Transfer in Production
Implementation notes from building an AI photo editor with Rork — non-destructive editing, background removal with fallbacks, style transfer, and picking preview resolution from device memory, with working code and the reasoning behind each call.
