Image processing

Definition

Image processing refers to the manipulation and analysis of images using algorithms and techniques to enhance, transform, or extract meaningful information from them. This field is a crucial component of computer vision, as it allows systems to interpret visual data and make decisions based on that information. Through various methods like filtering, edge detection, and image segmentation, image processing enables machines to analyze images similarly to how humans perceive and understand visual content.
