Cortex.Vision

Image and video processing for Cortex with transforms, augmentation pipelines, and ONNX model inference.

Part of the Cortex data science ecosystem for .NET.

Requires .NET 10+ and the Cortex core package. Video processing requires FFmpeg (or Apple AVFoundation on macOS).

Features

  • Image transforms — resize, crop, normalize, color conversion, and augmentation
  • Video processing — frame extraction and batch processing via FFmpeg and Apple AVFoundation
  • Augmentation pipelines — composable random transforms for training data
  • ONNX model inference — run vision models (classification, embeddings) directly on image DataFrames
  • Data loaders — batched, parallel image loading from directories

Installation

dotnet add package Cortex.Vision

Quick Start

using Cortex;
using Cortex.Vision;

var images = ImageDataFrame.LoadFromDirectory("dataset/train",
    resize: (224, 224), normalize: true);

var augmented = images.Transform(
    new RandomHorizontalFlip(),
    new RandomRotation(degrees: 15),
    new ColorJitter(brightness: 0.2));

var model = new OnnxVisionModel("resnet50.onnx");
var predictions = model.Predict(images);

Image Pipeline

var pipeline = new ImagePipeline()
    .Add(new Resize(224, 224))
    .Add(new Normalize(ImageNet.Mean, ImageNet.Std));
var processed = pipeline.Transform(images);

Video Frame Extraction

var frames = VideoIO.ExtractFrames("video.mp4", fps: 1);
var classified = model.Predict(frames);
