🌌 ZeroVision — High-Performance RAW & Image Processing Workstation

ZeroVision is a sovereign professional desktop workstation application (WPF, .NET 8) for high-fidelity image cataloging, RAW development, color grading, multi-frame computational photography, and computer vision acceleration. Part of the ZeroUniverse industrial computing ecosystem, it combines a non-destructive 32-bit float Linear Light develop pipeline with native DirectML ONNX AI engines and ergonomic industry-standard professional keyboard and workflow paradigms.

🌟 Key Capabilities

1. Professional Workstation Workflows & ZeroUI Controls

• Left Dock Navigator Panel: Fixed top widget with ZeroUI SegmentedControl (FIT | FILL | 1:1 | 2:1), live viewport rectangle tracking, and bi-directional real-time canvas pan/zoom.
• Library Metadata Drill-Down: 4-column filter bar (Date (Year) | Camera | Lens | ISO) with aggregate image counts and high-speed in-memory EXIF caching.
• Interactive Masking Gizmos: Direct canvas drag manipulation for Linear Gradient (start/center/end bars + rotation axis) and Radial Mask (center handle + 4 perimeter dimension handles + feather ring).
• Virtual Copies (Ctrl+'): Instant zero-byte branching with isolated edit histories and shared decoded proxies.
• Selective Copy Settings (Ctrl+Shift+C): Granular checklist dialog across 16 processing modules with Check All/None and persistent state.
• Auto-Advance Culling (Caps Lock): Hands-free keyboard workflow that automatically advances to the next photo when assigning ratings (0–5), flags (P/X/U), or color labels (6–9).
• Panel Toggles & Lights Out:
  • Tab: Toggle side panels.
  • Shift+Tab: Full clean canvas mode (hides titlebar, status bar, and filmstrip).
  • L: 3-stage Lights Out background dimming (100% -> Dim 80% -> Full Black 100%).
• Interactive Histogram Tone Zones: Real-time hover zone highlighting and direct drag tuning for Blacks, Shadows, Exposure, Highlights, and Whites.

2. Non-Destructive Develop Pipeline (32-bit Linear Light)

• Exposure & Tone: Exposure, Contrast, Highlights, Shadows, Whites, Blacks, Tone Curve (RGB & individual channels), Parametric Curves, Filmic RGB, Sigmoid, Dehaze, Auto Levels.
• Computational Photography & Multi-Frame Fusion:
  • Mertens Exposure Fusion (ExposureFusionService): Blends bracketed exposure sequences into high dynamic range imagery without tone-mapping halos using Contrast, Saturation, and Well-Exposedness weighting.
  • Multi-Band Focus Stacking: Laplacian pyramid frequency-band fusion with local energy computation for deep depth-of-field synthesis.
  • À-Trous Wavelet Denoising (WaveletDenoiseOp): Multi-scale $B_3$-spline wavelet decomposition with soft/hard thresholding for edge-preserving noise suppression.
  • Fast Marching Inpainting (AiInpaintOp): Telea fast marching algorithm for seamless defect, blemish, and watermark removal.
  • Edge-Preserving Smoothing & Noise Control: $O(1)$ Fast Guided Filter (GuidedFilterOp) and Directed Median Filter (DirectedMedianOp) for salt-and-pepper noise suppression.
  • Minkowski Gray-Edge AWB (AutoWhiteBalance): High-order derivative illuminant estimation for accurate color temperature recovery.
• Color & Color Grading: White Balance (Kelvin & Eyedropper), 8-Channel HSL Mixer + Targeted Adjustment Tool (TAT direct-canvas drag), 4-Way Color Balance, Split Toning, 3D LUT (.cube), Film Scan Negative Inverter.
• Detail & Corrections: Radius-based Sharpening with edge Masking, Multi-stage Denoise (Luminance, Color, Chroma), Lensfun auto-correction (distortion & vignetting), Perspective Upright, Liquify Warp.
• Local Adjustments: Linear Gradient, Radial, Brush, Polygon, Path, Luminance Range, Color Range, Parametric, and AI Subject/Sky masks.

3. Autonomous AI & Vision Pipeline

ZeroVision runs heavy AI workloads out-of-process via DirectML and ONNX Runtime:

AI Module	Architecture	Capability
Upscaler	Real-ESRGAN / AuraSR	2x / 4x super-resolution with GPU acceleration
Face Restorer	GFPGAN / CodeFormer	Portrait reconstruction and facial detail restoration
Vision Tagger	MobileNet / ResNet ONNX	Automated multi-label semantic tagging and classification
