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.

                                                                             megapixels with complex processing,
                                                                             while AI machine vision cameras can
                                                                                  reach up to 100 megapixels.








                  Some examples of AI applications based on Natural Language Processing 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.
