    Face recognition is the verification of a person by a machine using their facial features. It is a type of biometric identifier popularly used to authenticate users and for access control.   It uses the physical pattern of the face such as the eyes, lips, etc. to uniquely identify the person and convert it into a unique mathematical equation.   Working: Facial recognition works in three steps: detection, analysis and recognition. 1) Detection: The camera detects the face or finds the face in an image that may contain many faces be it in front or side profile using various algorithms and ML. One of the simplest features to detect in a face is the eyes, which are used by these algorithms to find a face. 2) Analysis: The image captured is analyzed. The software basically reads the geometry of our face i.e. distance between eyes, shape of cheekbones, depth of eye sockets, distance between nose and mouth and the contour of our ears, lips, chin etc. Ba...

  What is 3D Scanning? 3D Laser Scanning is a non-contact, non-destructive technology that uses a line of laser light to digitally capture the shape of physical objects. 3D laser scanners generate "point clouds" of data from an object's surface. In other words, 3D laser scanning is a method of capturing the exact size and shape of a physical object into the computer world as a digital 3-dimensional representation. 3D laser scanners capture free-form shapes and measure fine details to quickly generate highly accurate point clouds. 3D laser scanning is ideal for the measurement and inspection of contoured surfaces and complex geometries that require massive amounts of data for accurate description and where using traditional measurement methods or a touch probe is impractical.process :3D Laser Scanning Data Acquisition. CLASSIFICATION 1. No Contact Scanning: Millions of points on the xyz coordinate system can be easily captured via non-contact scanning. This data prov...

  ChatGPT is an artificial intelligence chatbot developed by OpenAI and launched in November 2022. It is built on top of OpenAI's  GPT-3 family of large language models and has been fine-tuned (an approach to transfer learning) using both supervised and reinforcement learning techniques. ChatGPT was launched as a prototype on November 30, 2022, and quickly garnered attention for its detailed responses and articulate answers across many domains of knowledge. Its uneven factual accuracy, however, has been identified as a significant drawback. Following the release of ChatGPT, OpenAI's valuation was estimated at US$29   billion in 2023 . Chat bots like GPT are powered by large amounts of data and computing techniques to make predictions to string words together in a meaningful way. They not only tap into a vast amount of vocabulary and information, but also understand words in context. This helps them mimic speech pat...
