- 4. • Computer vision (CV) is the object recognition. • It teaches the machine how to recognize the objects and react differently depending on the object classes. • Compared with the traditional computer vision algorithmic approach, it is difficult to cover all features extraction using an algorithmic approach because similar objects may have different features. • Deep convolution neural network (DCNN) does not require defining the features for object recognition. DCNN automatically updates the model parameters for feature extraction during the training.
- 5. o Object recognition is further divided into image classification, object localization, and object detection. o The image classification recognizes the objects in the image, and then assigns the class labels to the objects. o The object localization locates objects in the image and draws a bounding box around the objects. o Object detection combines both image classification and object localization. It can detect multiple objects in the image, estimate their size and position, and then draw the bounding box around the objects.
- 6. • The object detection can also generate the pixel-wise mask over the object to determine the exact object shape and called instance segmentation. It can further label each pixel in the image including the background and is called semantic segmentation.
- 7. o Gesture recognition in the retail market is expected to grow by 27.54% from 2018 to 2023. o The gesture-based interface allows the user to control different devices using hand or body motion. o It first captures the hand or body motion through the camera and then analyzes the motion in each frame. Through the machine learning model, it recognizes different motions and identifies the gesture, followed by the corresponding actions. o It is widely applied to home automation, and people can control home devices through gestures, activate the light, adjust the room temperature, and turn on/off the music system. o It can recognize individual family members and perform predefined actions based on personal history.
- 8. • Medical Diagnosis • Medical imaging (ultrasound, X-rays, computerized tomography scan – CT scan, and magnetic resonance imaging – MRI) is a useful cancer diagnosis tool. • Retail Applications • Retail also benefits from machine vision, which teaches the machine to recognize the items in the images and videos. It helps the retail to sell the products with better inventory control. Currently, 43% of retail artificial intelligence applications are related to machine vision. • Airport Security • Facial recognition is an important airport security application, especially for passenger processing. It quickly recognizes and validates the passenger’s identity and alerts the airport authority for security violations.
- 9. • Virtual Assistant • Language Translation
- 16. o Telemedicine: If the patients live in rural areas, they are geographically isolated from the healthcare facilities (clinic, laboratory, hospital). Artificial intelligence can solve problems and improve the quality of life. o Medical Imaging
