Recognize which country a flag image is for.

Classes

Details

  • This classifier is intended to be given an image of a flag pattern, not a flag in the wild.

Basic Examples  (2)

Use the "CountryFlag" built-in classifier to recognize a country from its flag:

Wolfram Language code: Classify["CountryFlag", [image]]

Classify multiple examples:

Wolfram Language code: Classify["CountryFlag", {[image], [image], [image], [image], [image]}]

Obtain a ClassifierFunction for the classifier:

Wolfram Language code: c = Classify["CountryFlag"]

Apply the classifier to a list of flags:

Wolfram Language code: c[{[image], [image], [image], [image], [image]}]

Scope  (1)

Load the ClassifierFunction corresponding to the built-in classifier:

Wolfram Language code: c = Classify["CountryFlag"]

Obtain a subset of possible classes using Information:

Wolfram Language code: Short[Information[c, "Classes"], 0.5]

Options  (2)

ClassPriors  (1)

Use a custom ClassPriors to restrict the possible outputs:

Wolfram Language code: Classify["CountryFlag", [image], ClassPriors -> <| Entity["Country", "SouthAfrica"] -> 0.95|>]

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold:

Wolfram Language code: Classify["CountryFlag", [image], IndeterminateThreshold -> 0.6]

Properties & Relations  (1)

The returned classes are "Country" entities:

Wolfram Language code: Short[Information[Classify["CountryFlag"], "Classes"], 1]

Neat Examples  (1)

Obtain different countries with their corresponding probabilities:

Wolfram Language code: probabilities = Classify["CountryFlag", [image], "Probabilities"];
