## Project Overview
AetherFloww is an autonomous public video incident intelligence and causal forensic reconstruction engine. Operating on public dashcam streams, bystander mobile recordings, and municipal cameras with zero private surveillance, the platform establishes why and how an accident or dispute occurred. The software deterministically filters out video game clips and CGI stunts, extracts pre-collision kinematics and trajectory vectors via Farneback optical flow, performs multimodal causal reasoning, anonymizes bystander PII via Gaussian blurring, and generates court-admissible forensic dossiers with SHA-256 digital chain of custody.

## The 85%+ Incident Reporting & Investigation Friction Gap
Across transportation safety audits, over 85% of acute hit-and-run collisions and highway incidents captured on civilian dashcams or bystander smartphones are never officially investigated with objective physical telemetry.
- **Citizen Interrogation & Judicial Friction:** Bystanders share video to public social networks but avoid dialing emergency lines or visiting police stations due to fear of grueling police interrogation, mobile phone confiscation, repeated court witness summons, harassment from opposing parties, and lost daily wages.
- **Cross-Jurisdictional Municipal & Precinct Border Disputes:** Dividing highway corridors and municipal borders frequently spark territorial debates between adjoining police precincts and county dispatch sectors, causing fatal delay while dispatch units dispute territorial responsibility.
- **Control Room & Investigation Manpower Constraints:** Municipal emergency command centers (911 / 112 CAD dispatch desks) and police investigation units handle thousands of cases and lack the manpower to manually inspect millions of video frames. Unfiltered keyword scrapers generate thousands of false alarms from video games, movie stunts, and comedic sketches.

## Verification Pipeline & Causal Forensic Architecture

### 1. Ingestion & Kinematic Optical Flow
- **Ingestion:** Zero-disk RAM streaming buffer at 1 FPS keyframe intervals (0 KB disk writes).
- **Farneback Optical Flow:** Computes dense velocity vector fields $u(x, y, t)$ across consecutive frames on GPU Tensor Cores.
- **Jitter Compensation:** Global affine homography matrix $H_{affine}$ computed across background keypoints to subtract handheld camera shake and vehicle vibration.
- **Deceleration Gating:** Identifies localized deceleration gradients $\|\nabla u\| > 3.5\text{ m/s}^2$ paired with radial crowd scatter vectors.

### 2. Multi-View Epipolar Geometry & 3D Deformation
- **Epipolar Geometry:** Validates cross-frame keypoint consistency via fundamental matrix constraint $x'^T F x = 0$.
- **Plastic Deformation:** Evaluates non-elastic 3D vehicular contour volume reduction ($\Delta V_{contour} > 15\%$) to verify authentic sheet-metal crumpling.
- **Synthetic Media Rejection:** Automatically detects and rejects rigid-body video game physics (e.g. GTA V, BeamNG.drive), polygonal clipping, and 2D CGI compositing stunts.

### 3. Mel-Spectrogram Siren & Impact Acoustics
- **Audio Processing:** 16 kHz sampling, 512-point FFT window Mel-spectrogram analysis.
- **Siren Sweeps:** Identifies continuous sinusoidal 700 Hz to 1500 Hz siren wails and yelps.
- **Impact Transients:** Detects impulsive broadband glass-shatter and sheet-metal crumpling transients (>85 dB sound pressure level, <50ms rise time).
- **Soundtrack Suppression:** Filters out background music, soundtrack layering, and comedic speech overlays.

### 4. Multimodal Causal Reasoning & Contributing Causal Factors Taxonomy
Performs multimodal visual causal reasoning (Gemini / DeepSeek / Qwen) to classify exact incident causation:
- **Red-Light & Signal Violations:** Breaching active red or late amber signal phases.
- **Illegal U-Turns & Prohibited Turns:** Unlawful turns across unbroken double-yellow medians or divided highway curbs.
- **Sudden Lane Cuts:** Abrupt unsignaled lane transitions across solid markings into vehicle stopping paths.
- **Driver Speed Disparity:** Excessive velocity relative to corridor design speed or surrounding traffic flow.
- **Brake Lockup & Skid Marks:** Loss of control, sudden hard braking skid dynamics, or steering mechanical failure.
- **Mechanical Failure:** Tire blowouts, axle detachment, or brake failure prior to impact.
- **Road-Rage Dispute Initiation:** Intentional brake-checking ("swoop-and-squat" insurance fraud), aggressive tailgating, or physical altercations.

### 5. PostGIS Precinct Spatial Routing
- **Visual OCR:** Extracts route milestone markers, transit interchange shields, gantry signage, and regional vehicle registration codes.
- **Spatial SQL:** Executes `ST_Contains` spatial polygon queries against official municipal police precinct GIS boundary polygons (e.g. Central Metro Precinct, North Expressway Sector, West District Patrol).
- **Boundary Road Handling:** Dual-tags border incidents within 100 meters of a dividing line with a "Boundary Corridor Incident" flag.

### 6. Standardized Incident Dossier, Privacy & Legal Custody
- **Packet Structure:** Calibrated chronological MP4 packet containing pre-impact approach, collision point, and aftermath.
- **Privacy-by-Design Masking:** Edge-based YOLOv11x automated Gaussian blurring on all bystander faces and uninvolved civilian license plates (0 KB unredacted PII stored).
- **Cryptographic Digital Evidence Certificate:** Stamped with an immutable cryptographic SHA-256 hash digest, source ingress URL, and UTC ingestion timestamp, satisfying electronic evidence admissibility requirements under Section 63 Bharatiya Sakshya Adhiniyam (BSA) 2023 in India, US Federal Rules of Evidence FRE 902(13)/(14), and ISO/IEC 27037 / NIST SP 800-86 standards.

## Built for Four Anchor Stakeholders
1. **Police Traffic Accident Investigators & Law Enforcement:** Delivers verified incident video packets and Section 63 BSA dossiers with precise territorial precinct coordinates directly to police CAD consoles, accelerating charge-sheets and eliminating witness subjectivity.
2. **Municipal Road Safety Engineers & Highway Authorities (NHAI / State DOTs):** Aggregates collision causation vectors across corridors to identify dangerous road geometry flaws, blind corners, and signal timing defects.
3. **Insurance Adjusters & Claim Evaluators:** Provides deterministic fault apportionment (e.g. 75% primary fault / 25% contributory speed) and instant detection of staged collisions ("swoop-and-squat" fraud).
4. **News Channels & Broadcast Media Newsrooms:** Supplies newsrooms with verified, timestamped, un-tampered public video feeds with immutable proof of provenance and location, eliminating the danger of broadcasting fake or re-uploaded viral hoaxes.

## Operational Reality: Why Deterministic Automation Matters
- **Forensic Processing:** Deterministic pre-collision trajectory and causal breakdown in minutes (manual engineering analysis takes weeks per collision).
- **Fatigue-Free Uptime:** 24/7 continuous autonomous monitoring without human cognitive fatigue.
- **False Alarm Suppression:** > 94% rejection of non-incident videos, video game simulations, and CGI stunts.
- **Evidence Integrity:** Immutable SHA-256 digital certificate of electronic custody under Section 63 BSA, FRE 902, and ISO/IEC 27037 standards for court and newsroom provenance.
