Efficiency in imaging

Image compression is a process that reduces the file size of images by removing redundant information, which helps in saving storage space and improving transmission speed. It can be lossy or lossless, where lossy compression sacrifices some image quality for greater size reduction, while lossless compression retains all original data.

Image quality refers to the perceived clarity, detail, and visual fidelity of an image, often influenced by factors such as resolution, color accuracy, and noise. It is crucial in various fields such as photography, medical imaging, and digital media, where high image quality can significantly impact the effectiveness and interpretation of visual information.
