This article is about template matching in digital image processing. For template matching in psychology, see Template matching theory.
Template matching[1] is a technique in digital image processing for finding small parts of an image which match a template image. It can be used for quality control in manufacturing,[2] navigation of mobile robots,[3] or edge detection in images.[4]
The main challenges in a template matching task are detection of occlusion, when a sought-after object is partly hidden in an image; detection of non-rigid transformations, when an object is distorted or imaged from different angles; sensitivity to illumination and background changes; background clutter; and scale changes.[5]
