bildförbättringsalgoritmer

bildförbättring is a Swedish term that translates to "image enhancement" in English. It encompasses a range of techniques used to improve the visual quality of digital images. These techniques aim to correct imperfections, bring out details, or alter the aesthetic appearance of a photograph or graphic.

Common image enhancement processes include adjusting brightness and contrast to make an image clearer or more dramatic. Color correction is another frequent step, addressing issues like white balance to ensure colors appear natural or to create a specific mood. Sharpening can be applied to reduce blur and make edges more defined, while noise reduction aims to remove unwanted graininess or speckles that can appear in low-light conditions or with high ISO settings.

Advanced bildförbättring might involve retouching to remove blemishes or unwanted objects, selective color adjustments to emphasize certain hues, or even artistic filters to transform an image. Software applications ranging from professional-grade programs like Adobe Photoshop to simpler mobile apps offer a variety of tools for performing these enhancements. The goal is typically to make an image more pleasing to the eye, more informative, or more suitable for its intended purpose, whether that be for printing, online display, or artistic expression.
