A caricature is a rendered image showing the features of its subject in a simplified or exaggerated way through sketching, pencil strokes, or other artistic drawings (compare to: cartoon).
In modern usage, 'caricature' is used predominantly for a portrait of a recognizable individual (much as originally used to describe the works of Pier Leone Ghezzi), while the more recent term 'cartoon', popularised in the 19th century from its use in Punch magazine, is used for any other form of comic image, including political satire.
Some of the earliest caricatures are found in the works of Leonardo da Vinci, who actively sought people with deformities to use as models.
[3][citation needed] Caricature became popular in European aristocratic circles, notably through the works of the Italian Rococo artist Pier Leone Ghezzi.
[citation needed] and the fashion spread to Britain from visitors returning from the Grand Tour; the much greater freedom of the press in England allowed its use in biting political satire and furthered its development as an art form in its own right.
[4] In the 18th century, because of England's liberal political traditions, relative freedom of speech, and burgeoning publishing industry, London was a hot bed for the development of modern forms of caricature.
Caricature became a valuable tool for political campaigning and both Gillray and Rowlandson established their reputations as caricaturists working as 'hired guns' in the 1784 Westminster election.
[6] Their skills continued to be in high demand; in the turbulent period of the French Revolution and Napoleonic Wars caricature became an increasingly important communication medium.
[10] Drawing caricatures can simply be a form of entertainment and amusement – in which case gentle mockery is in order – or the art can be employed to make a serious social or political point.
Brennan's system implemented this idea in a partially automated fashion as follows: the operator was required to input a frontal drawing of the desired person having a standardized topology (the number and ordering of lines for every face).
[citation needed] On the other hand, Liang et al.[16] argue that caricature varies depending on the artist and cannot be captured in a single definition.
For example, most systems are restricted to exactly frontal poses, whereas many or even most manually produced caricatures (and face portraits in general) choose an off-center "three-quarters" view.
