A Novel Image Enhancement Method of 3-D Medical Images by Transforming the 3-D Images to 2-D Grayscale Images

The proposed method is a novel image enhancement for color medical images. In this method, the 3-D medical image is transformed first to the 2-D grayscale image and then the enhancement algorithms, either in frequency domain or spatial domain, are applied to the grayscale image. This paper describes the enhancement effects on the medical images by the proposed transformation model and then the enhancement by the alpha-rooting method, for the frequency domain algorithm, and the histogram equalization, for the spatial domain enhancement algorithm. The enhancement is quantitatively measured with respect to the metric which is called the color enhancement measure estimation (CEME). The proposed method is showing good CEME values as compared to the original images.
