One common tool used to improve early images results is image enhancement. We are not the only ones who employ this technology; it is applied in other fields like those utilized in the industrial, military, and medical fields, among many others. Our goal in this paper is to suggest an effective method for medical picture contrast. Contrast enhancement on photos is a preprocessing phase that helps make other images more efficient for tasks like pattern recognition and computer vision, rather than a highly processed step. The suggested method uses homomorphic filtering and DC adjustment to improve contrast while maintaining brightness in the provided image.

摘要

One common tool used to improve early images results is image enhancement. We are not the only ones who employ this technology; it is applied in other fields like those utilized in the industrial, military, and medical fields, among many others. Our goal in this paper is to suggest an effective method for medical picture contrast. Contrast enhancement on photos is a preprocessing phase that helps make other images more efficient for tasks like pattern recognition and computer vision, rather than a highly processed step. The suggested method uses homomorphic filtering and DC adjustment to improve contrast while maintaining brightness in the provided image.
