image - Computer Vision and Image Recognition algorithms for R users

This repository contains a suite of R packages which perform image algorithms currently not available in other R packages like magick, imager or EBImage.

These algorithms are put into different packages because of license differences. Currently the following R packages are available:

  • image.CornerDetectionF9: FAST-9 corner detection for images (license: BSD-2). More info
  • image.LineSegmentDetector: Line Segment Detector (LSD) for images (license: AGPL-3). More info
  • image.ContourDetector: Unsupervised Smooth Contour Line Detection for images (license: AGPL-3). More info
  • image.CannyEdges: Canny Edge Detector for Images (license: GPL-3). More info
  • image.dlib: Speeded up robust features (SURF) and histogram of oriented gradients (HOG) features (license: AGPL-3). More info
  • image.darknet: Image classification using darknet with deep learning models AlexNet, Darknet, VGG-16, Extraction (GoogleNet) and Darknet19. As well object detection using the state-of-the art YOLO detection system (license: MIT). More info

More packages and extensions are under development.
