The precise feature extraction of small details from images of the human body is considered a challenge since fine details like small nodules and delicate vasculature are hard to see while the computed tomography scan is being conducted due to low contrast. Although various contrast enhancement methods have been introduced for better visibility of the images, they generally introduce more noise and edge artifacts. In this paper, a self-supervised Deep Perceptual Enhancement Network with an Artificial Protozoa Optimizer named APO-DPENet is proposed for optimizing the parameters of the image effectively. The results comparing the proposed method with other methods show a PSNR of 25.75308 dB, an SSIM of 0.95894, a CEI of 0.91385, and an EPI of 0.98960 units. The results indicate better contrast retention and edge preservation of the proposed method, along with improved noise removal capabilities. This suggests that the proposed method is robust enough for analysis.
