Data is avaialable in many formats like Text, Images, Video etc given belwo is the list of common data we see in day to day life. and to process such type of data you need to know image and video processing. For handling such type of data we use image processing and to analyse it we use ComputerVision

Computer Vision is a subset of Artificail Intelligence which can be trained on images for successful prediction. I will be using OpenCV for image processign and Computer Vision.
