Details enhancement of MRI image using illumination and reflectance estimation

摘要

This paper presents new details enhancement of Magnetic Resonance Imaging (MRI) image using illumination-reflectance estimation. The illumination is estimated using cost parameter linked with the luminance function. The estimated illumination is piecewise spatially smoothed that eliminates the halo artifacts in the MRI images. The illumination dynamic correction and details improvement are achieved through edge preserving low pass filter. The proposed method is adjusted such that the contrast of the spinal cord images is improved and assists the radiologists in making correct decisions. It is clear from the experimental results presented that the proposed method outperforms and is superior to other researcher's method.
