    Convolutional Neural Network (CNN) helps a machine learning model to process the image by
                     breaking it down to pixels. It then transforms it into digital data by applying algorithms before
                     comparing the captured images with those stored in the database. These systems are used to
                     identify an individual based on their facial features like spacing of eyes, ears, chin, etc.

                     Some examples of AI applications based on computer vision are as follows:
                       Face recognition systems used at workplace and schools to mark attendance.
                       Biometric software is used by law enforcement agencies to scan faces in CCTV footages.
                       Image enabled searches are initiated at online shopping websites using camera.

                        Selfie-based authentication is initiated for banking and payments app using face recognition
                       technology.

                     NATURAL LANGUAGE PROCESSING
                     Natural  Language  Processing  (NLP) is the ability  of an AI system  to  understand  human
                     language as it is spoken. Computer cannot understand the language we speak. Hence, we need
                     software and programming languages to communicate with the computer.

                     NLP helps the machine understand the natural languages of humans. It gives us an opportunity
                     to speak to the machine in our language.
                     NLP works by  breaking-down  a language  into  shorter elementary  pieces  to  understand  the
                     relation between the pieces and explore how these pieces work together to create meaning.

                                                                                 The human eye is estimated at 576
                                                                                megapixels with complex processing,
                                                                                while AI machine vision cameras can
                                                                                    reach up to 100 megapixels.

                     Some examples of AI applications based on NLP are as follows:
                        Chatbot  applications  that  interact  with humans are available  all the  time  which helps the
                       customers resolve their queries, thus improving the customer's experience.
                        Translation tools such as Google Translate and Microsoft Translate helps in translating the local
                       language for a tourist.

                       Personal assistant applications such as Google Assistant, Siri and Alexa also use NLP.
