Triaging a storm-damaged neighborhood by the share of each roof that is gone

A mask on the missing shingles and a mask on the roof plane beneath it, so the property worth an adjuster first is the one the percentage names.

Improving a custom object detection model, the tactics that still move the number

Two thousand frames from the real line beat ten thousand from a bench, a written box rule beats a talented labeler, and curation is a job that never finishes.

Dataset health check for computer vision, what to look at before anything trains

A scratch dataset where every scratch sits in the centre of the frame will train a model that looks in the centre. Five counts to read before the first epoch.

Few-shot image labeling on a vial tray, one box drawn and the rest proposed

Draw one box on a vial, let the tray fill with proposals, and give a person the last word on each before the batch commits. The fastener bin is the hard case.

AI data labeling workflows, three ways to label footage and when each one pays

A pipeline right-of-way survey labeled three ways: every box by hand, Lexi proposing and a person checking, and synthetic frames for the leak nobody has filmed.

Annotation analytics, the numbers a labeling queue produces besides labels

Computer vision heatmaps drawn from the aisle cameras a store already has

Footpoints from every tracked box, aggregated over a day and mapped onto the floor plan, show where footfall goes. A camera nudged in cleaning shifts the map.

Computer vision safety triggers that stop the machine when what should be there is not

Hands off the palm buttons, a spotter missing, a person down on the belt. The trigger is an absence held past a window, and a dropped frame never stops a line.

OCR on video, reading a container number from a moving truck

A yard camera tracks each container as it passes, reads the ID panel on the sampled frames, and takes a vote. One blurry frame never becomes a wrong record.

Railway safety with trackside cameras, zones and a signaller who can live with the alerts

Medical device label inspection reads the lot number only after finding the label

A detector finds the label, a question reads the crop, an implausible value goes to a person, and the two stages are scored apart so you know which to fix.

Reducing computer vision inference costs when a store watches every aisle all day

The bill for watching a camera is set by how often you look, what you decode, and where the model runs. Most of a store's frames need no model at all.

Two stages to read a plate, and why each needs its own score

A gate camera boxes the plate, then reads the characters. Score the two stages apart, or a rainy night's wrong read cannot tell you which one failed.

Process compliance tracking with a camera, each step in order and for long enough

A model classes each step of a procedure per frame, a timer turns frames into a duration, and a rule fires when a step is skipped or cut short, frames attached.

F1 score in computer vision, the failure that accuracy hides on the inspection line

Fifty porous welds in ten thousand parts make accuracy meaningless. F1 balances what was found against what was right, and the threshold is what moves it.

Missing vs null annotations, an empty frame is a label and a forgotten box is a lie

An empty corridor, a defect-free shift and a stocked shelf are labels on purpose. A frame where someone forgot the box looks identical and teaches the opposite.
