Introduction to Computer Vision

Computer vision gives machines the ability to interpret visual information — yet seeing is far harder than it looks. This chapter maps the full landscape of CV tasks (classification, detection, segmentation, keypoints, tracking), shows how images become tensors of numbers, and identifies the core challenges — occlusion, lighting, scale, and inference speed — that make the field genuinely difficult.
