When creating virtual backgrounds on the web, we encountered the problem of unclear edges of portraits. What parameters can be optimized. const optimizedVirtualBg = VirtualBackground( '/path/to/background.jpg', { qualityLevel: 'accurate', // 最高精度 outputCategoryMask: true, // 启用分类蒙版 outputConfidenceMasks: false // 减少噪声 }, (stats) => { // 实时监控处理质量 console.log(

处理时间: ${stats.processingTimeMs}ms

); }, { assetPaths: { tasksVisionFileSet: '/mediapipe/wasm', modelAssetPath: '/mediapipe/models/selfie_segmenter.tflite' } } );
