13-13: Hyphenate "k-means-based" for clarity.Compound adjectives preceding a noun should be hyphenated: "k-means-based colour clustering" (not "k-means based").
24-27: Reduce word repetition for better flow.The three bullet points (lines 24–26) each begin with "You," which makes the text feel repetitive. Consider restructuring to vary the sentence openings:
🔎 Suggested revision
- You have an RGBA image stored in a tightly-packed `uint8_t*` pixels buffer (4 bytes per pixel, row-major). - You need to remove very small connected components while preserving large components. - You are OK with replacing a small-region pixel by the color of an *adjacent* large region. + You have an RGBA image stored in a tightly-packed `uint8_t*` pixels buffer (4 bytes per pixel, row-major). + This approach requires removing small connected components while preserving large ones. + It replaces each small-region pixel with the color of an adjacent large region.docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/connected-components.md (1)
45-46: Standardize spelling: "labeled" vs. "labelled".The file mixes American ("labeled" at line 13, 39) and British ("labelled" at line 46) spellings. Choose one variant and use it consistently throughout. Since the C++ source uses "labeled," prefer the American spelling.

16-18: Reduce adverb repetition in the 4-connectivity section.The section heading and opening sentence both use "only," which is redundant. Restructure to vary the phrasing:
🔎 Suggested revision
-## Only 4-connectivity -Components connected only diagonally will be considered separate. +## 4-Connectivity +Components connected only diagonally will be treated as separate.
39-40: Use a stronger descriptor than "very large."Replace the weak intensifier "very" with a more specific or meaningful term:

50-71: Add language specification to mermaid code block.Line 51 opens a fenced code block for a mermaid diagram but doesn't specify the language. Add
mermaidto the opening fence:🔎 Suggested fix
- <TabItem value="flowchart"> - ```mermaid + <TabItem value="flowchart"> + ```mermaidThe opening should be
```mermaidon line 51 (or ensure the code block explicitly includes the language identifier).Note: Verify that your Markdown renderer properly recognizes the
mermaidlanguage tag. If it's already correct in the source, this hint may be a false positive from the linter.docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/faq.md (1)
27-27: Tighten phrasing: simplify "exactly the same"The phrase "exactly the same RGBA values" is slightly wordy; "the same RGBA values" is sufficient since RGBA equality is inherently exact.
🔎 Proposed refinement
- All pixels have **exactly the same RGBA values** + All pixels have **the same RGBA values**

1-21: Clear and rigorous complexity analysis.The explanation of time and space complexity is accurate and well-presented. The notes on cache behavior and alternative algorithms add practical value for implementers.
docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/testing-and-debugging-suggestions.md (1)
1-23: Practical and actionable testing guidance.The suggestions for synthetic test images, visualization, and instrumentation are well-organized and will help developers validate their implementations effectively.

1-57: Comprehensive and technically sound enhancement strategies.The variants section provides clear, actionable alternatives with appropriate code examples and mathematical notation. The cross-reference to Limitations & Pitfalls adds valuable context.
docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/faq.md (1)
1-363: Comprehensive FAQ with clear explanations and honest design tradeoffs.The documentation is well-structured, technically sound, and appropriately candid about the function's limitations (e.g., lack of parallelization, bounding-box-only shape validation, no topology preservation). The Q&A format, visual diagrams, and complexity analysis make it accessible to both users and maintainers.
The coverage spans fundamental concepts (4-connectivity, pixel indexing), algorithm design rationale (two-pass labeling/merge), performance characteristics (O(n) time, predictable memory), and practical guidance (when to use/avoid). A strong addition to the documentation suite.

25-30: Consider simplifying "exactly the same" for conciseness.The phrase "exactly the same RGBA values" could be more concise. Since the context already emphasizes exact equality in the next sentence, consider simplifying to "identical RGBA values" or "same RGBA values."
🔎 Proposed improvement

24-26: Simplify "very small" to strengthen the language.The intensifier "very" weakens the description. Since the context clearly indicates small, pixel-level components, "very" is redundant. Removing it makes the statement more direct.

- To remove very small connected components while preserving large components. + To remove small connected components while preserving large components.

1-120: Documentation is clear, comprehensive, and well-structured.The algorithm explanation progresses logically from high-level overview through mathematical formalism. SVG diagrams effectively illustrate 4-connectivity and pixel neighborhoods. Mathematical notation is properly formatted and the rationale for design choices (4-connectivity vs. 8-, local pixel-wise merging) is well-explained.
docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/faq.md (1)
1-362: Comprehensive FAQ with clear technical depth.The FAQ covers essential questions methodically, from problem definition through determinism guarantees. Mathematical notation is consistent, SVG examples clarify visual concepts (indexing, holes, color similarity), and edge cases (hollow rings, no-big-neighbors fallback) are properly documented. The closing summary ties everything together effectively.
docs/docs/reference/wasm/modules/image/mergeSmallRegionsInPlace/overview.md (1)
33-67: Clear API documentation with proper preconditions and postconditions.The function signature is well-documented with inline parameter descriptions. The rationale for requiring all three evaluation criteria (minArea, minWidth, minHeight) to pass is explicitly stated, preventing common misunderstandings. LaTeX notation for the pixel buffer layout is clear, and the important caveat about unsuitability (exact RGBA equality, no fuzzy matching) is properly positioned to guide users away from incorrect use cases.
