Introduction to Computer Vision - from A16Z - AI Playbook

There are AI areas focused on different senses, but vision is fundamental along with natural language. Vision attempts to identify and extract symbols from raw visual data and then use those symbols to make decisions, take actions or produce information. These symbols have many forms: they can be labels from a set used for training, captions, text extracted from the image via OCR, colors, and so on. Not all images are created alike: In general, systems that are good at processing attributes for still images are not necessarily as good for processing video, and vice-versa.
