At a Glance
• Computer Vision is a part of Artificial Intelligence (AI) that focuses on helping machines understand and
interpret visual information like images and videos.
• Image processing involves manipulating and enhancing images to improve their quality or extract specific
features.
• Computer Vision is used in many fields, like healthcare, shopping, and entertainment.
• Facial recognition is a technology that uses Computer Vision to identify and verify people based on their
facial features.
• Face filters in Computer Vision are fun and interactive tools that uses algorithm to detect and track facial
features.
• Classification is the process of determining the class or category of an input image.
• Localisation means where the object is located in the image.
• Object detection is the process of identifying or detecting the instances of real-world on which the detection
model has been trained.
• Instance segmentation is the process of dividing an image into smaller segments to identify individual
objects within it, distinguishing them from the background or other objects in the image.
• An image is a visual representation of any object.
• Pixel is the smallest unit of information in a digital image.
• Resolution is basically the dimensions through which you can measure how many pixels are on a screen or
an image.
• Grayscale images are images made up of different shades of gray, ranging from black to white, but without
any colour.
• All coloured images around us are made up of 3 primary colours of Red, Green and Blue.
• A No-Code AI tool is a software platform that allows users to build, deploy, and manage Artificial Intelligence
(AI) models without writing any code.
• Lobe is a user-friendly, no-code AI tool designed to make it easy for anyone to create AI models without
needing programming skills.
• Orange is a powerful, open-source data visualisation and analysis tool, widely used in data mining and
Machine Learning.
