calculateCCFmaxSearch: Compute maximum correlation for two images, taking into...

In xhtai/cartridges: Algorithm to Compare Cartridge Case Images

Description

This is an updated version of calculateCCFmax(). It normalizes the images after rotation (mean 0, variance 1), and uses a slightly different grid search to reduce runtime.

Usage

calculateCCFmaxSearch(image1, image2, pad = TRUE)

Arguments

image1	first image matrix
image2	second image matrix. The two images do not need to be the same size.
pad	logical value for whether the smaller image should be zero-padded. The default is TRUE. Only set this to FALSE if the images are of the same size and are square.

Value

A list with four items: 1) maximum correlation taking into account many possible rotations and translations of the second image, 2) the corresponding dx, the horizontal translation, 3) dy, the vertical translation, and 4) theta, the corresponding rotation angle.

Examples

## Not run: 
calculateCCFmaxSearch(processedExample, processedExample2)
