Cover factor & open area
Optical open area, pore size distribution, and cover uniformity measured on the actual fabric.

Example outputs shown for illustration. Numbers depend on your samples and protocol.

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.

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.
What this result does not establish: Reports optical open area measured from transmitted-light images. This is a geometric measurement, not an air-permeability test; correlate it against your permeability method before using it as a substitute.
The measurement, today
Cover and openness are usually inferred from construction arithmetic or an air-permeability reading. Neither tells you where the fabric is open, or how the pores are distributed.
What it costs
Cover drives opacity, air permeability, hand, and print quality. Where a fabric is unexpectedly open, prints bleed and coatings strike through, and the fault is only found after finishing.
From image to reviewed result
- 1
Backlight the fabric
Capture a transmitted-light image so interstices read bright against the yarn.
- 2
Threshold the openings
Adaptive thresholding separates open interstices from yarn, without a fixed global cutoff.
- 3
Measure the pores
Each opening is measured for area and equivalent diameter; the distribution and median pore follow.
- 4
Map uniformity
Open area is reported per tile across the field so thin and dense regions are visible.
