Geometric Transformation and Image Registration
The toolbox supports functions to perform simple geometric transformations, such as resizing, rotating, and cropping, as well as more complex affine and projective geometric transformations. The toolbox also provides tools for aligning a pair of images automatically using intensity correlation, feature matching, or control point mapping techniques.
Categories
- Common Geometric Transformations
Resize, rotate, crop, and translate images
- Generic Geometric Transformations
Perform generic geometric transformations using theimwarpworkflow
- Image Registration
Align two images using intensity correlation, feature matching, or control point mapping
Featured Examples
Resize an Image
Change the size of an image by specifying a multiplicative scale factor or by specifying the desired output size of the image.
Register Two Images Using Spatial Referencing to Enhance Display
Use spatial referencing objects to understand the spatial relationship between two images and to display the images effectively.
Use Phase Correlation as Preprocessing Step in Registration
Use phase correlation to estimate an initial transformation when images are severely misaligned.
