OpenCV-Flow allows you to create components with custom input and sources.
Below is the component created to process the Add operator from the opencv.js.
export class PlusComponent extends CVFComponent { //Node inputs definitions targets: TargetHandle[] = [ { title: "src1", position: Position.Left }, { title: "src2", position: Position.Left }, ]; //Node outputs definitions sources: SourceHandle[] = [ { title: "out", position: Position.Right } ];
static processor = class PlusProcessor extends CVFNodeProcessor { async proccess() { const [src1, src2] = inputs; //Inputs from targets definitions const out: Mat = new cv.Mat(src1.rows, src1.cols, src1.type(), new cv.Scalar(0));
cv.add(src1, src2, out);
this.sources = [out];//same number of outputs as sources definitions this.output(out); } };}The "targets" and "sources" properties indicate the inputs required by the component and which outputs will be made available. It is possible to indicate the position of the component's "targets" and "sources" through the "position" property.
Possible positions:
enum Position { Left = "left", Top = "top", Right = "right", Bottom = "bottom"}OpenCV-Flow possui código livre
