Image enhancement refers to the process of improving the visual quality of an image. This can involve adjusting brightness, contrast, and color balance to make the image clearer and more appealing. Techniques such as sharpening and noise reduction are commonly used to highlight important features and reduce unwanted artifacts. Various tools and software, like Adobe Photoshop and GIMP, are available for image enhancement. These programs allow users to apply filters and effects, making it easier to achieve the desired look. Image enhancement is widely used in photography, medical imaging, and satellite imagery to improve the interpretation and analysis of visual data.
