Abstract

This paper presents a new adaptive retinex scheme in order to enhance Magnetic Resonance Imaging (MRI) spinal cord medical images. The illumination is estimated using cost parameter linked with the luminance function. The estimated illumination is piecewise spatially smoothed that eliminates the hal artifacts in the images. The illumination dynamic correction and details improvement are achieved through edge preserving low pass filter. The proposed method improves the details such that contrast of the spinal cord images is adaptively enhanced and helps the doctors to make the right decisions. It is clear from the experimental results that the presented that the proposed method outperforms and is superior to other researcher’s method.
