The recognition of flags requires the provision of a database of flags and to obtain manually or automatically data on them (their layout, size, colors, etc.)
The search criteria can be various: first the colors (red, white, blue, etc.), then the content layout: horizontal or vertical bands, cross, diagonal, etc. but also if drawn elements have been added like coats of arms, weapons, animals, stars, crosses, triangles or other geometric figures etc.
Example: A flag with 3 horizontal bands from left to right: blue, white, red. This is the flag of France
