In `@docs/docfx/articles/guides/pixel-access.md`:
- Around line 68-73: Add a grayscale Mat declaration directly in the RowSpan
example before accessing grayscale.RowSpan<byte>(0), using a single-channel type
such as CV_8UC1 and dimensions appropriate for the snippet. Keep the existing
first-row access and fill operations unchanged.
In `@docs/docfx/articles/guides/video-io.md`:
- Around line 67-80: Update the video-writing flow to read and validate the
first frame before constructing VideoWriter; derive frameSize from that frame’s
Width and Height, write the first frame, then continue reading and writing
subsequent frames without dropping it.

Migrates the useful parts of the stale Wiki into maintained DocFX guides. Pixel access, image conversion, video I/O, file storage, and histograms are rewritten for OpenCvSharp5, while the old per-algorithm feature pages are consolidated into one feature detection and matching guide.
Adds new task-oriented guides for Mat fundamentals and a complete image-processing pipeline. Obsolete platform tutorials, the removed debugger visualizer, and small DFT, Subdiv2D, and equation snippets are intentionally not copied because they are outdated or provide little OpenCvSharp-specific guidance. The repository instructions now also record the Label and assignee convention for agent-created PRs and issues.
