comparison: Compute correlation for two images

In xhtai/cartridges: Algorithm to Compare Cartridge Case Images

Description

Given two processed (and possibly rotated) images, compute the cross-correlation function and return the largest correlation value and its associated translation parameters.

Usage

comparison(image1, image2)

Arguments

image1	first image matrix
image2	second image matrix. Note that the two matrices have to be the same size.

Value

A list with three items: 1) maximum correlation taking into account all possible translations, 2) dx, the horizontal translation corresponding to the maximum correlation, and 3) dy, the vertical translation corresponding to the maximum correlation.

Examples

## Not run: 
comparison(processedExample, processedExample2)

## End(Not run)
