CVFIOComponent are components with only one data input and one data output.
Most OpenCV-Flow components were created with this component. It is component ideal for adding a standalone processor node.
Below is the component created to process the Sobel edge detector from the opencv.js library.
export class SobelComponent extends CVFIOComponent { static processor = class SobelProcessor extends CVFNodeProcessor { async proccess() { this.sources = []; for (const src of this.inputs) { const dst = new cv.Mat(src.rows, src.cols, cv.CV_8UC1);
cv.cvtColor(src, src, cv.COLOR_RGB2GRAY, 0); cv.Sobel(src,dst, cv.CV_8U, 1, 0, 3, 1, 0, cv.BORDER_DEFAULT);
this.sources.push(dst); this.output(dst); } } };}OpenCV-Flow possui código livre
