Registration Estimator

Register 2-D grayscale images


The Registration Estimator app aligns 2-D grayscale images using automatic image registration. Using this app, you can:

  • Compare feature-based, intensity-based, and nonrigid registration techniques interactively

  • Obtain the registered image and the geometric transformation

Feature-Based Techniques

Registration Estimator app offers six registration techniques that use feature detection and matching:

  • FAST

  • MinEigen

  • Harris


  • SURF

  • MSER

Intensity-Based Techniques

Registration Estimator app offers three registration techniques that use intensity metric optimization:

  • Monomodal intensity

  • Multimodal intensity

  • Phase correlation

For more details of the available techniques, see Techniques Supported by Registration Estimator App.

Open the Registration Estimator App

  • MATLAB® Toolstrip: On the Apps tab, under Image Processing and Computer Vision, click the Registration Estimator app icon.

  • MATLAB command prompt: Enter registrationEstimator.

Programmatic Use
