IPLab.Core

The core library for IPLab — a C# image-processing pipeline engine built on OpenCvSharp4.

It provides:

  • Built-in image-processing operators (load, blur, threshold, detect circles, find contours, etc.)
  • A flow data model (FlowDef) for defining operator graphs as JSON
  • A runtime executor (FlowEx) that resolves dependencies, runs operators in topological order, and stores intermediate results

Install

dotnet add package IPLab.Core

Quick start

using IPLab.Core;

// Load a saved flow from JSON
var flow = FlowDefSerializer.Deserialize(File.ReadAllText("my-flow.ipl"));

// Execute it
var executor = new FlowEx(flow);
await executor.RunAllAsync(CancellationToken.None);

// Read a result
var image = executor.IntermediateResults["O1"]["Image"] as Mat;

Building flows in code

See scripts/Waviness/ for a complete example: it defines and runs an IPLab flow entirely from C# code, executes it via FlowEx, and reads the intermediate results.
