matchTemplate: Template Matching

In neuroconductor-releases/Rvision: Basic Computer Vision Library

Description

matchTemplate compares a template against overlapping image regions using the specified method. After the function finishes the comparison, the best matches can be found as global minimums (when methods "SQDIFF" or "SQDIFF_NORMED" were used) or maximums (when methods "CCORR", "CCORR_NORMED", "CCOEFF" or "CCOEF_NORMED" were used) using the minMaxLoc function.

Usage

matchTemplate(image, template, method, mask = NULL)

Arguments

image	An Image object.
template	An Image object of the same type as image. template cannot be larger than image.
method	A string indicating the comparison method to use. It can be any of the following (see https://bit.ly/2RjELvJ for a full description of each comparison method): "SQDIFF" "SQDIFF_NORMED" "CCORR" "CCORR_NORMED" "CCOEFF" "CCOEFF_NORMED"
mask	An Image object of the same type and dimensions as template (default: NULL). mask is currently only supported when SQDIFF and CCORR_NORMED are used.
