Registro de imagen
Alinee dos imágenes mediante técnicas de correlación de intensidades, coincidencia de rasgos o correspondencia de puntos de control
En conjunto, Image Processing Toolbox™ y Computer Vision Toolbox™ ofrecen cuatro soluciones de registro de imagen: registro interactivo con la app Registration Estimator, registro automático basado en la intensidad, registro basado en puntos de control y coincidencia automática de características. Si necesita ayuda para seleccionar un enfoque, consulte Approaches to Registering Images.

Temas
Registro interactivo de imágenes
- Register Images Using Registration Estimator App
Align a pair of images using feature-based registration techniques in the Registration Estimator app.
- Techniques Supported by Registration Estimator
The Registration Estimator app provides algorithms for feature-based, intensity-based, and nonrigid registration.
Registrar imágenes con la optimización basada en intensidades
- Intensity-Based Automatic Image Registration
Intensity-based automatic image registration uses a similarity metric, an optimizer, and a transformation type to register two images iteratively. - Create an Optimizer and Metric for Intensity-Based Image Registration
Select an image metric and an optimizer suitable for either monomodal or multimodal images. - Use Phase Correlation as Preprocessing Step in Registration
Use phase correlation to estimate an initial transformation when images are severely misaligned. - Registering an Image Using Normalized Cross-Correlation
Determine the translation needed to align a cropped subset of an image with the larger image.
Registrar imágenes con la correspondencia entre puntos de control
- Control Point Registration
To determine the parameters of a geometric transformation, you can pick corresponding pairs of points in two images. - Geometric Transformation Types for Control Point Registration
Control point registration can infer the parameters for similarity, affine, projective, polynomial, piecewise linear, and local weighted mean transformations. - Control Point Selection Procedure
To specify control points in a pair of images interactively, use the Control Point Selection Tool.
- Use Cross-Correlation to Improve Control Point Placement
Fine-tune your control point selections using cross-correlation.
