kuvanparannuksen

Kuvanparannus, also known as image enhancement, refers to a set of techniques used to improve the visual quality or interpretability of an image. These methods aim to correct undesirable distortions, flaws, or to emphasize specific features within an image. The goal is not to alter the fundamental content of the image but rather to make it more suitable for a particular application or for human perception.

Common kuvanparannus techniques include adjusting brightness and contrast to make details more visible, sharpening to reduce blurriness, and noise reduction to remove unwanted grain or speckles. Color correction is another important aspect, ensuring that colors are rendered accurately or aesthetically pleasingly. Geometric transformations can also be considered part of image enhancement, such as rotating, scaling, or correcting perspective distortions.

Kuvanparannus finds applications in a wide range of fields. In photography, it is used to refine digital photos. In medicine, it enhances the clarity of X-rays, MRIs, and other diagnostic images, aiding in diagnosis. In remote sensing and satellite imagery, it helps to bring out land features or atmospheric conditions. For surveillance and security, improved image quality can be crucial for identification. Digital forensics also relies on kuvanparannus to recover details from damaged or low-quality images. The specific techniques employed depend heavily on the type of image and the desired outcome.
