Computer vision uses digital computer techniques to extract, characterize, and interpret information in visual images of a three-dimensional world. The goal of computer vision is primarily to enable engineering systems to model and manipulate the environment by using visual sensing. The field of computer vision can be characterized as immature and diverse. Even though earlier work exists, it was not until the late 1970s that a more focused study of the field started when computers could manage the processing of large data sets such as images
