Optical Flow Field

An optical flow field represents the pattern of motion in a sequence of images, showing how objects or textures move between frames. Imagine watching a video and seeing arrows indicating the direction and speed of different parts of the scene—this is what an optical flow field visualizes. It helps computers understand movement, such as tracking a person walking or a car driving, by calculating the subtle shifts in pixel patterns over time. Essentially, it maps out the flow of visual information, providing insight into how a scene changes frame-to-frame.
