OpenCV Computer Vision Skill

Comprehensive computer vision and image processing using OpenCV WebAssembly.

Trigger When

使用此技能的场景：

图像处理 / Image Process：resize（调整大小）、blur（模糊）、threshold（阈值）、morphology（形态学）、sharpen（锐化）、crop（裁剪）、stats（统计）

目标检测 / Detection：cascade（级联检测）、dnn/YOLO（深度学习检测）、hog、contour（轮廓）、circle（圆检测）、line（直线检测）

特征提取 / Features：orb、sift、akaze、match（特征匹配）、homography（单应性）、optflow（光流）、template（模板匹配）

图像拼接 / Stitching：panorama（全景拼接）、stitch（多图拼接，扫描件模式）

照片处理 / Photo：denoise（降噪）、inpaint（修复）、stylize（风格化）、hdr、pencil（素描）、detail（细节增强）

相机标定 / Calibration：chessboard（棋盘格）、undistort（去畸变）、corners（亚像素角点）、pose（位姿估计）

机器学习 / ML：train-knn（训练KNN）、train-svm（训练SVM）、predict（预测）、kmeans（聚类）

批处理 / Batch：batch-process（批量处理）、batch-convert（格式转换）、batch-stats（批量统计），支持多线程

Prerequisites

Required plugin: openclaw-wasm-sandbox

WASM file: ~/.openclaw/skills/opencv/files/opencv-component.wasm

- Download if missing:

    openclaw wasm-sandbox download \
      "https://raw.githubusercontent.com/guyoung/wasm-sandbox-openclaw-skills/main/opencv/files/opencv-component.wasm" \
      "~/.openclaw/skills/opencv/files/opencv-component.wasm"
    

Tool

Use wasm-sandbox-run tool with the WASM file:

wasm-sandbox-run({
  wasmFile: "~/.openclaw/skills/opencv/files/opencv-component.wasm",
  args: ["", ...args]
})

For file access, use workDir or mapDir to expose directories to the sandbox.
