ANTRIX AWM · MEASUREMENT ENGINE

Sub-Pixel Accuracy,
Proven.

Antrix AWM (Adaptive Window Moments) is our proprietary sub-pixel edge localization engine, benchmarked against eight established detection methods and built to stay accurate where classical methods fail.

Every optical measurement system lives or dies on one number: how precisely it can locate an edge.

Antrix AWM finds edge, hole, and gap boundaries to a small fraction of a pixel.

It was benchmarked head-to-head against eight established sub-pixel detection methods across thousands of simulated measurement trials, and it keeps its accuracy in conditions where most edge detectors quietly fail: noisy images and closely-spaced edges.

WHY IT MATTERS

Where Others Fail, It Holds.

Best Overall Accuracy, No Calibration Needed

Lowest combined bias + noise error of any tested method on straight edges, curved edges, and corners alike, with expanded uncertainty as low as 0.26 px in low-blur conditions.

Best-in-Class on Closely-Spaced Edges

Where two boundaries sit near each other, bore holes, slots, thin features, Antrix AWM stays accurate down to gaps where every classical moment-based method breaks down completely.

Real Improvement Where It Counts

On two-edge and narrow-feature geometries, Antrix AWM measurably outperforms the previous best-in-class method, with up to ~20% lower measurement uncertainty.

Sub-Micron-Class Repeatability

Pixel-locking, the bias that repeats at the same sub-pixel phase, sits at the noise floor of what is measurable. No detectable systematic error tied to where an edge falls within a pixel.

Bias-variance Pareto position

Antrix AWM's position on the accuracy/stability frontier against eight established detectors.

Two-edge breakdown

Measurement safety as edges move closer together, Antrix AWM stays reliable at gaps where classical methods fail.

Recommended detector by scenario

Where Antrix AWM is the top pick across real-world measurement scenarios.

Detector accuracy by edge radius

Accuracy holds steady across edge curvature, from tight corners to near-straight edges.

WHERE IT FITS

Built Into Every Antrix Measurement.

Caliper-jaw and gauge-style dimensional measurement, bore and hole diameter inspection, PCB trace width and spacing verification, and any machine-vision application where sub-pixel precision on a live camera feed, not a lab microscope, needs to be trustworthy.
