Artificial  Intelligence  is  the  process  of  simulating  human
                  intelligence by machines. It is an approach to enable computers
                  or robots or any machine to think just like a human.
                  The  main  aim  of  AI  (Artificial  Intelligence)  is  to  improve  a
                  computer’s functions that are related to human knowledge, for
                  example, reasoning, learning and problem solving.

                  AI and Facial Detection


                  Using AI, we can create programs that can identify the face of a person, or detect the person's facial
                  features such as nose, eyes, lips, etc. The real life example of this is the face mask detection robots
                  that are used during COVID-19 to detect whether a person is wearing the face mask or not.
                  In AI Connect also, we can create programs to detect whether a person is wearing the face mask or
                  not, or whether a person is wearing sunglasses or not, etc.

                  Face Mask Detection in AI Connect

                  To create a program to detect if the person in the image is wearing a face mask or not, create a
                  project in AI Connect. Create AI Coding activity in this project. Then, follow the given steps:

                   Step 1    Drag and drop Load Image block from Facial Features sub-category (mentioned under AI

                           Learning category).

                   Step 2    Attach if-do block from Logic category. This Block is used as the conditional block. If, if
                           condition is satisfied it gives the output as mentioned in the do part, otherwise it gives the
                           output mentioned in else part.

                   Step 3   Attach "==" block from Logic category inside the if-do block.

                   Step 4    Attach Get nose count block from Facial Features sub-category to the left end of "=="

                           block. This block is used to detect a person's nose.

                   Step 5    Similarly, attach numeric block ("0" block) from Input category to the right end of “==”
                           block.

                            (If the person is wearing a mask, then his/her nose will not be displayed so, the nose count
                           will be 0, otherwise the person is not wearing the mask.)


                                                                 Notes

                         If, you click on the arrow of Get nose count block, the drop-down menu will appear
                         from where you  can choose other facial parts as well, such as eyes, smile, face, etc. It
                         can be use to detect other part of face as well.


                   Step 6   Click on Setting button of if-do block and add else block to it.
