Approach
Template matching can be subdivided between two approaches: feature-based and template-based matching. The feature-based approach uses the features of the search and template image, such as edges or corners, as the primary match-measuring metrics to find the best matching location of the template in the source image. The template-based, or global, approach, uses the entire template, with generally a sum-comparing metric (using SAD, SSD, cross-correlation, etc.) that determines the best location by testing all or a sample of the viable test locations within the search image that the template image may match up to.

Famous quotes containing the word approach:
“The modern world needs people with a complex identity who are intellectually autonomous and prepared to cope with uncertainty; who are able to tolerate ambiguity and not be driven by fear into a rigid, single-solution approach to problems, who are rational, foresightful and who look for facts; who can draw inferences and can control their behavior in the light of foreseen consequences, who are altruistic and enjoy doing for others, and who understand social forces and trends.”
—Robert Havighurst (20th century)
“Oh! mystery of man, from what a depth
Proceed thy honours. I am lost, but see
In simple childhood something of the base
On which thy greatness stands; but this I feel,
That from thyself it comes, that thou must give,
Else never canst receive. The days gone by
Return upon me almost from the dawn
Of life: the hiding-places of man’s power
Open; I would approach them, but they close.”
—William Wordsworth (1770–1850)
“To approach a city ... as if it were [an] ... architectural problem ... is to make the mistake of attempting to substitute art for life.... The results ... are neither life nor art. They are taxidermy.”
—Jane Jacobs (b. 1916)
