Results

Each measurement below comes from your own images, tied back to the annotated frame it came from, so results stay comparable across samples, locations, and conditions.

µm or count

Orientation tensor

Size and shape measured for every detected object, then summarized across the population.

Illustrative shape

In your report: Per-object table, size distribution, and summary percentiles.

% area

Fiber area %

Segmented area of the feature divided by the eligible area in the two-dimensional image.

Built around your image set

Use the calibrated images your team already collects, together with the locations you need to compare.

01
Representative images
Provide representative optical cross-section images with a recorded scale calibration and the regions of interest clearly visible.
02
Image capture details
Record instrument, magnification, pixel scale, preparation method, and the smallest feature the review must resolve.
03
What to compare
State the samples, number of fields, and conditions to compare. A single field of view is not treated as a whole-sample result by itself.

Each report includes

The artifacts your team receives, ready for review and archive.

Annotated image set

Original images with regions of interest, measurement points, masks, and finding overlays.

Measurement table

Location-indexed values, units, distributions, and QC flags in a structured export.

Method record

Calibration evidence, analysis settings, version history, and validation summary.

Confidence in every resultTraceable measurements, reviewed against your agreed reference method.
Traceable scale
The report records the image scale, calibration evidence, and a method-specific expanded measurement uncertainty. It does not use one product-wide accuracy number.
Reference comparison
The configured method is compared with your accepted reference method or reviewed annotations, and reports bias by measurement range and image condition.
Detection performance
Detections are evaluated against reviewed reference regions with precision, recall, and segmentation overlap, separated by the conditions that affect performance.
Repeatability
The locked protocol is rerun on the same inputs and on a defined repeat set. The review records variation from image acquisition, sampling, and analysis separately where possible.

The measurement, today

Composite performance hinges on fiber orientation and voids, but manual angle measurement covers only a handful of fibers.

From image to reviewed result

  1. 1

    Calibrate the scale

    Set spatial scale from a bar or known dimension. Every downstream number inherits real units.

  2. 2

    Detect & segment

    Segmentation models find the objects and regions of interest: grains, particles, pores, fibers, cells.

  3. 3

    Measure

    Quantify size, count, area fraction, density, and orientation. The metrics your method already defines.

  4. 4

    Review the overlay

    Inspect the result on every field. Adjust thresholds by hand; the change is logged with the output.

  5. 5

    Export & compare

    Publication-ready statistics, plus batch comparison across lots, conditions, and time points.
