Image processing is a field of computer science and engineering that focuses on the analysis, manipulation, and enhancement of digital images using various algorithms and techniques. It involves the interpretation of visual information from images to extract useful data, detect patterns, and make decisions based on the analysis. Image processing is used in a variety of applications, including medical imaging, satellite imagery analysis, facial recognition, and quality control in manufacturing. The goal of image processing is to improve the quality of images, enhance visual information, and extract meaningful data for further analysis and decision-making.
