TSFI & DCI

A freshness score, and the confidence behind it.

Every TuaiSegar assessment pairs a TSFI Freshness Score with a Data Confidence Index, so you always know how much weight to place on the result.

TuaiSegar Freshness Index

What TSFI measures.

TSFI is a 0–100 summary of the visible freshness characteristics observed in your photo, together with any contextual information you provide.

80–100

Fresh

Strong visible condition with no significant defects observed.

65–79

Good

Generally sound with minor visible wear or early ripening signs.

50–64

Use soon

Visible decline that suggests a shorter usable window.

Below 50

Declining

Clear visible deterioration in the submitted image.

Assessment factors

Visible characteristics considered in every score.

These are visible assessment factors observed from the submitted image. TSFI does not measure internal produce quality.

Colour consistency

Visible colour range and evenness across the produce surface.

Surface quality

Skin texture, gloss, shrivelling and visible surface damage.

Hydration or wilting

Signs of moisture loss such as limp leaves or soft skin.

Bruising and visible defects

Dark patches, cuts, mould-like marks and other visible defects.

Stem or leaf condition

Condition of stems, calyx and leaves where visible.

Packaging condensation

Moisture build-up inside packaging that may affect shelf life.

Ripeness indicators

Visible cues that suggest ripening stage for that produce.

Data Confidence Index

Know the score—and how much confidence to place in it.

The Data Confidence Index communicates the strength of the visual and contextual evidence used to produce each assessment.

Low DCI example

DCI 48%

Retake the photo in brighter lighting and include more of the produce surface.

DCI describes evidence strength for a visual assessment. It is not a measure of scientific or laboratory certainty.

TSFI evaluates visible characteristics from submitted images and available contextual information. Results are estimates intended to support purchasing and quality-screening decisions. They do not replace physical inspection, laboratory testing or food-safety assessment.
