PIC platform

From cabin video to physiological signal.

PIC applies computer vision and physiological modelling to subtle temporal changes in facial video, producing an estimated signal together with the quality information needed to interpret it responsibly.

Signal pipeline

A software layer, designed around automotive constraints.

The algorithm is only one part of the system. Image formation, illumination, compression, motion, face coverage and compute placement all affect whether a useful signal is available.

01 / CAPTURE

Video input

Receive suitable facial video from a cabin camera or evaluation camera.

02 / QUALITY

Frame assessment

Assess face visibility, motion, lighting and other conditions relevant to signal extraction.

03 / INFERENCE

Physiological model

Estimate heart-rate-related information from temporal visual patterns.

04 / OUTPUT

Signal + confidence

Expose the estimate alongside quality and availability for downstream fusion.

Dynamic monitoring

Real vehicles make physiological sensing harder.

Camera-based physiological monitoring depends on subtle temporal information. Driving adds motion, vibration, rapid illumination changes and image-pipeline effects that can obscure the signal.

MOTION

Driver and vehicle movement

Head turns, facial movement, road vibration and relative camera motion introduce artefacts that must be separated from physiological change.

LIGHT

Changing illumination

Sun, shadow, tunnels, night lighting and reflections alter exposure and spectral conditions from moment to moment.

IMAGE PIPELINE

Signal preservation

Frame timing, exposure, gain, denoising, compression and ISP processing can preserve—or remove—the information required for estimation.

±2 BPM

Steady environment

Observed heart-rate accuracy under evaluated steady conditions.

±5 BPM

Real driving conditions

Observed across evaluated driving conditions varying in speed, road surface and lighting.

Performance figures describe evaluated conditions. Results depend on the camera, image pipeline, subject visibility and operating environment; target-platform validation remains essential.

Model approach

Built from physiological video intelligence—not a generic face feature.

FaceMed’s broader platform experience in multimodal clinical AI informs the discipline behind PIC: temporal modelling, large-scale physiological video learning, reviewable output and explicit limits.

TEMPORAL

Signals evolve over time

PIC analyses temporal visual information rather than a single still image.

QUALITY-AWARE

Availability is an output

A useful automotive component must be able to communicate uncertainty and non-availability.

PLATFORM-SPECIFIC

Integration changes performance

Every sensor, illumination and ISP combination requires evidence on the target platform.

Integration boundary

A physiological input—not an independent vehicle decision.

PIC has a defined role in the cabin stack. It processes suitable facial video and exposes an estimate with quality information; the OEM or integrator owns fusion, HMI, fallback and response policy.

01 / INPUT

Camera stream

Facial video, timing metadata and an agreed image pipeline.

02 / PIC

Physiological engine

Quality assessment, inference and signal-availability logic.

03 / OUTPUT

SDK or API

Estimated signal, trend, confidence and availability fields.

04 / OEM

Fusion and policy

Behavioural fusion, verification, HMI, fallback and response.

Validation & evidence

Match every claim to the evidence behind it.

Signal accuracy, vehicle robustness, application validity and production assurance answer different questions. A credible programme establishes them in sequence.

LEVEL 1

Signal feasibility

Compare the physiological estimate against an agreed reference.

LEVEL 2

Vehicle robustness

Test motion, vibration, illumination and occupant variation.

LEVEL 3

Use-case validity

Establish whether the signal improves the defined workflow.

LEVEL 4

Production assurance

Address programme, safety, cybersecurity, privacy and regulatory requirements.

ACCURACY

Reference comparison

Error distribution, agreement bands and results broken down by protocol and condition.

AVAILABILITY

Signal quality

Usable time, time to estimate, degraded states and recovery after difficult conditions.

ROBUSTNESS

Failure modes

Transparent analysis of motion, light, occlusion, face coverage, camera and ISP sensitivity.
