Final answer:
Identi-Kit uses a feature-based assembly process to create facial composites by allowing users to select and adjust various standardized facial features from a database.
Step-by-step explanation:
The primary method used in Identi-Kit for creating facial composites is a feature-based assembly process. This system allows a user, often a law enforcement officer or a witness, to construct a face by choosing from a range of facial features such as different types of eyes, noses, mouths, and so on. The features in an Identi-Kit are typically based on a database of clear and standardized facial components.
Users can adjust and manipulate these features to resemble a suspect's appearance as closely as possible. Over the years, Identi-Kit has been modernized and now often includes computerized systems that provide even more detailed control over the creation of the facial composites.
