In computer vision, a feature is a measurable piece of information that represents a specific aspect of an image or video. Features can be low-level, like edges and corners, or high-level, such as shapes and semantic objects, depending on the complexity of the analysis. Traditional features, such as SIFT, HOG, and SURF, are manually designed algorithms that identify patterns in the data. For example, corners in an image may indicate object boundaries, and gradients can reveal textures. These features are essential for tasks like object detection and matching. Modern deep learning methods extract features automatically through neural networks. For instance, convolutional layers in a CNN capture hierarchical features that make it easier to identify objects or classify scenes. These features play a crucial role in applications ranging from facial recognition to autonomous driving.
