The study looked at improving image contrast, which aims to enhance image quality and make details clearer. The focus of this study was on improving image contrast using three main algorithms: Histogram Equalizer, ACE Mean, and Hybrid ACE-FireFly. Histogram Equalizer is a classic method that distributes color frequency evenly, enhancing contrast and enhancing details, while ACE Mean relies on mathematical integration and optimization techniques to enhance image quality and make contrast more pronounced. Hybrid ACE-FireFly represents a cross between ACE, a traditional method, and FireFly. It is an intelligent algorithm to improve contrast using the advantages of each.

Common metrics such as PSNR, MSE, and RMSE were used to evaluate the image quality. PSNR reflects the effectiveness of algorithms in providing image quality, as the values increase when the quality is better. Also, MSE is measured by the difference between the actual values of the pixels in the image, and low values indicate high quality. RMSE is used to determine the extent of deviation between the two images. The results show noticeable improvements in image quality using the adopted algorithms, and the metrics used reflect an improvement in contrast and quality of details in the processed images.

Ten images of different contrast were tested to verify the performance efficiency of the proposed algorithm. The results indicate that the proposed hybrid method was the best among similar methods used.
