2. Domain : Computer Vision (CV)

Computer Vision (CV) : "It is a process of capturing, processing and analysing real world images and videos to allow machines to extract meaningful informations from the physical world."

Some applications of CV are:-

• Web : face recognition, object recognition, geolocalization, Google maps, Youtube - content categorization etc.
• Smartphones : QR codes, face detection, Snapchat filters, Google Lens, Expression detection (Smile), Android lens blur, iphone portrait mode etc.
• Medical imaging : MRI, assisted diagnosis, automatic pathology, AI-guided surgery etc.
• Media : virtual sports replay, visual effects for film etc.
• Insurance : claims automation, damage analysis, property inspection etc.
• Health Care : analyzing health records, lab reports, x-ray images, etc.
• Automobiles : Self driving cars etc.

Some Challenges using Computer Vision are as following:

• Collection of facial, location, or biometric data raises privacy concerns and misuse of such data may raise privacy and ethics issues.
• DeepFakes generates the realistic but fake images/videos which can spread the misinformation, fraud, and loss of digital trust.
• Undesired situations like for facial recognition, poor lightening, expression, clothing on face, motion blur etc. can confuse the model. Hence, it can reduced the accuracy./li>
