There are efforts to provide caricatures automatically or semi-automatically victimization lighting tricks techniques. as an example, a system proposed by Akleman et al.[13] provides warp tools specifically designed toward quickly producing caricatures. There are only a few computer code programs designed specifically for mechanically creating caricatures.

Computer graphic system requires quite different skill sets to design a caricature as compared to the caricatures created on paper. so employing a laptop in the digital production of caricatures needs advanced data of the program's practicality. instead of being an easier technique of caricature creation, it are often a more complex methodology of making images that feature finer coloring textures than will be created victimisation additional traditional ways.

[http://www.aaacaricatures.com caricatures] A milestone in formally defining caricature was Susan Brennan's master's thesis[14] in 1982. In her system, caricature was formalized because the method of exaggerating variations from a median face. as an example, if Prince of Wales has a lot of outstanding ears than the common person, in his caricature the ears are going to be a lot of larger than normal. Brennan's system enforced this idea in a very partly machine-controlled fashion as follows: the operator was needed to input a frontal drawing of the desired person having a regular topology (the variety and ordering of lines for each face). She obtained a corresponding drawing of an average male face. Then, the particular face was caricatured just by subtracting from the actual face the corresponding point on the mean face (the origin being placed within the middle of the face), scaling this distinction by an element larger than one, and adding the scaled distinction back onto the mean face.

Though Brennan's systematisation was introduced within the Eighties, it remains relevant in recent work. Mo et al.[15] refined the idea by noting that the population variance of the feature should be taken into account. For example, the distance between the eyes varies less than other features such as the size of the nose. Thus even a small variation in the eye spacing is unusual and should be exaggerated, whereas a correspondingly small change in the nose size relative to the mean would not be unusual enough to be worthy of exaggeration.
