Színátalakítás

Színátalakítás, in English color transformation, refers to the process of altering the color values of an image. This can involve changing the hue, saturation, lightness, or combinations thereof. Color transformation is a fundamental operation in digital image processing and computer graphics, used for a wide variety of applications.

One common application is color correction, where images are adjusted to compensate for poor lighting conditions or inaccurate camera settings. This can involve making colors appear more natural or enhancing specific colors for artistic effect. Another use is in image editing, where users can apply filters or effects to change the overall mood or style of an image. For example, a sepia tone effect is a form of color transformation that gives an image an antique appearance.

In scientific imaging, color transformation can be used to visualize data that is not inherently visible to the human eye. For instance, infrared or ultraviolet imagery can be mapped to visible colors to highlight specific features or phenomena. Color spaces themselves, such as RGB, CMYK, or HSV, are different ways of representing color, and transformations between these spaces are often necessary for tasks like printing or display. The specific algorithms used for color transformation vary depending on the desired outcome and the color model being employed.
