The TwinStack ANPR dashboard: a Lahore street clip with cars, bikes and trucks boxed and their number plates read, next to a feed of detected plates with crops.
06Computer vision & AI · 2026

TwinStack ANPR

Automatic number plate recognition for Pakistani vehicles. Upload a CCTV clip or a photo and every vehicle is detected and tracked while a plate detector and an OCR model we trained ourselves read its number plate. Readings feed a live dashboard with a searchable vehicle log, entry/exit parking sessions with fees and watchlist alerts.

  • Vehicle detection and tracking with YOLO11 and ByteTrack: cars, bikes, buses and trucks keep one ID through the clip
  • Plate detector trained on 1,578 photos of Pakistani plates (Punjab, Sindh, Islamabad, KP): precision 1.00, recall 0.97 on held-out photos
  • OCR model fine-tuned on 1,471 hand-checked plate crops: on vehicles it never saw in training it reads 88% of plates fully correct, up from 79%

Three Sketchify app screens: the studio home with a photo turning into a sketch, the editor showing a cat in the Graphite style, and the same photo in the Watercolour style.
07AI & image processing · 2026

Sketchify

An AI image-processing app that turns photos into drawings. A computer-vision pipeline — edge detection, Gaussian and difference-of-Gaussians filtering, tone mapping — runs as GPU shaders on the phone, so thirteen sketch styles update live while the sliders move and no photo is ever uploaded. Built with React Native and Expo.

  • Computer-vision pipeline on the GPU: Sobel edge detection, Gaussian and difference-of-Gaussians filters, colour-dodge tone mapping and halftone screening, written as SkSL shaders
  • Real-time image processing: a full-resolution preview redraws as the sliders move, and exports go up to 4096 px
  • Thirteen styles, from graphite, pencil and ink to cross-hatch, comic, watercolour and neon
