«Brightness is one of the most important characteristics of pixels. It is involved in many image editing algorithms, such as contrast or shadow/highlight» [7, p.117]. Changing the brightness of grayscale images is important because it improves overall visibility and clarity. In addition, it can improve detail and contrast, thereby making it easier to perceive and differentiate the various components of the image. In addition, this technique can also help correct any exposure issues or lighting inconsistencies in the original image, ensuring that it is displayed accurately and correctly. In this paper, we propose to use the firefly algorithm with a linear interpolation method to adjust the brightness of grayscale images.
