Abstract

In this study, a novel conjugate coefficient that is especially intended to address picture restoration
issues is presented within the context of the conjugate gradient approach. Stability and dependability are ensured throughout the iterative process by the suggested method, which not only ensures
global convergence but also upholds the crucial descent feature. The results of extensive numerical
studies show that the new method regularly performs better than conventional tactics. Significant
gains in computing efficiency and restoration accuracy are particularly evident when compared to the
traditional Fletcher-Reeves (FR) conjugate gradient approach. With better performance in iteration
reduction, function evaluations, and feature retention, our results show that the improved conjugate
gradient approach is a reliable and efficient tool for high-quality picture reconstruction.
